/R [316 73 572 791 ] When you hit a ball just right, you've hit it on one of the three "sweet spots" of the bat. The bat barrel initially bends backwards away from the ball while the handle bends outward and the vibration in the handle causes the players top hand to lose contact with the handle. | This cookie is set by GDPR Cookie Consent plugin. Learn how the sweet spot correlates with movement and vibration. Otherwise, the effective
mass of the bat is less than its whole mass. A paper on this
subject can be downloaded here. When a wake is pushed down, a fastball is pushed up. A superball has a COR of about 0.9, a baseball has a COR of
about 0.5 and a sorbothane ball has a COR of about 0.1 (ie it hardly bounces at
all). For example, a 33-inch bat with a -3 rating weighs 30 ounces. /Gamma [1.8 1.8 1.8] When it comes to bats, one inch in length is equivalent to an ounce of weight. A bat that is too light also hampers the development of a solid, level swing. The shoulders reach maximum speed first. Theres a certain romance to wooden baseball bats that goes away the second you swing one. During the fraction of a second after the ball hits the bat, the ball compresses as the energy of the motion is absorbed by the ball, causing it to become elastic potential energy. But its not that simple. >> Second, we give a simplified abstract form of bat which facilitates the description and modeling study. Boxing. Then can't we add to the list of deeper queries some of . The impacts were at
distances of 2, 7, 12, 17, 24 and 31 cm from the end of the barrel. << /P 17 0 R This is similarly done for tennis rackets and baseball bats. The experiment described below would be an ideal
project on the physics of baseball, for any high school or University physics
student. 1 inch in length is huge. Impact at the end of the bat (outside the sweetspot) causes the bat to vibrate violently after the collision. The same thing
happens when swinging a golf club, but it is not a well-known effect. 24 0 obj /Width 77 The sweet spots location for maximizing how far the batted ball travels after being hit can be calculated scientifically. Since F =
m*dv/t, we can integrate the force waveform to measure ball speed vs time, then
integrate v = dx/dt to measure the shift in the ball CM vs time. Washington State University Sports Science Laboratory, You can get into the real nitty gritty of the science of MOI including complex equations by clicking through to the complete Bat-Ball Science Mass Moment of Inertia article, but well put it in laymans terms. A simple introduction to the physics of the collision problem
is given here. In order to determine how each of the sweet spots influences the "feel" of the bat, measurements were made of the impact forces transmitted to the hands. He received his Ph.D. in physics from the University of California, Berkeley, where he conducted research on particle physics and cosmology. Hence, there
are two vibration nodes in the barrel. By combining the results of these two separate
experiments, we can then work out what happens when a bat is swung at an incoming
ball. Sniper Skin Announces Their Newest Partnership with Bassmaster Opens Pro, Briana Tucker! Adding to that is the fact that, When a ball player hits the ball with the bat, it produces an enormous amount of force on the bat in a split second the impact could mean up to. However, the COP shifts a long way toward the
handle when a batter holds the handle, and plays only a minor role in the feel
of the bat for an impact at the sweet spot. The ball rotated more than 1/4 but less than 1/2 of one
revolution from one frame to the next, each frame being 0.04 sec apart. It is almost as
easy as walking. The sweet spot of a baseball bat, like that of a tennis racket, can be defined either in terms of a vibration node or a centre of percussion. The mass moment of inertia (MOI) is a measure of the distribution of mass in the bat. })(); Designed by Elegant Themes | Powered by WordPress, The Ultimate Guide to Baseball-Themed Online Slot Games, How To Hem Baseball Pants: A Step-by-Step Guide For Customizing Your Look. /P 14 0 R This is due to the fact that the collision is able to create a larger transfer of energy when the bat and ball are in perfect alignment. By understanding the physics of baseball bats, players can maximize their performance on the field. The bat and the forearms are locked at right angles at the beginning of
the swing, by locking the wrists, otherwise the bat would start to rotate in
the wrong direction at the beginning of the swing. Balls compress along the same F vs x curve,
regardless of the ball speed, although the actual compression curve for a given
ball will depend on its stiffness. Although the Hickory bat wood is the most difficult to swing, it is also the most powerful, making it the hardest of all bat wood species. /R [316 73 572 791 ] Reflexes. Just look for ovals going around each other. The sweet spot of a bat exists because bat vibrations are not excited significantly at that spot. Subscribe to get special offers, free giveaways, and once-in-a-lifetime deals. >> When a player has a bad hit and fails to hit the "sweet spot", it causes vibrations which can cause the bat to bend or break. The flight of a
ball through the air depends strongly on how fast it spins, and in what
direction it spins. However, it will also feel heavier when swung. For small swings of a pendulum, the incoming and outgoing speed of
the pendulum bob is proportional to its horizontal displacement, so the
relevant ball speed ratios can be measured directly off the film with a ruler. /R [52 73 308 791 ] By coupling the flexible bat to the ball via a parametrized fo. Ash bats, on the other hand, are more flexible, making them perfect for contact hitters. Pitching Mechanics.- 6. If the bat approaches a ball incident at speed vin
then. When you hit the sweet spot, the bat feels the best in your hand. This is why it is important that baseball bats are made out of a hard material that can maximize the energy transfer while also reducing the risk of injury to the player. If the ball is also mounted as a pendulum. These cookies track visitors across websites and collect information to provide customized ads. At the major league level, maple bats now account for 75% to 80% of all bats. The
whole mass of the bat is not involved in the collision, unless the collision
happens to occur at the centre of mass of the bat. So, after a rainy day game, ensure your bat is dry before you store it. Lighter bats, on the other hand, are better suited for contact hitters who are looking to make contact with the ball and generate less power. We also use third-party cookies that help us analyze and understand how you use this website. Good eyesight. /P 26 0 R We offer our conclusions in Section 6. It was there that he first had the idea to create a resource for physics enthusiasts of all levels to learn about and discuss the latest developments in the field. Similar results
are obtained at much higher ball speeds, the forces and x values being
correspondingly much larger. Explains r. cross, "the sweet spot of a baseball bat," american journal of physics, 66, 772-779. /R as well as the force at right angles to that, given
by M (dV/dt). Check out Sniper Skin's easy to install, weatherproof and dural bat grips here! Articles may contain affiliate links which enable us to share in the revenue of any purchases made. Rather,
most coaches and others think in terms of wrist torque, which is probably much
too small to provide the necessary large couple near the end of the swing The
couple must come mainly from the two arms, not the wrists. A lot has been learned over the years but more experiments need to
be done to better understand how the ball bounces and how much spin it acquires
when it bounces. 6 0 obj Jessy is an avid baseball fan and writer for the popular website, Baseball Writes. 13 0 obj Cylinder 2 (500

(recorded with a signal generator connected to a speaker). Step up to the batters box and get warmed up for the physics of baseball bats with this great video from ESPN Sports Science. At one point, called the node, the waves always cancel each other out. There is a greater amount of strength required to swing a wood bat, but the ball exits faster when hit. When it comes to the distance traveled by a ball, speed and speed at which it sails off the bat are all important factors. Scientifically speaking, this is the weakest part of a wooden baseball bat. What is velocity of bullet in the barrel? The sweet spot of a bat exists because bat vibrations
are not excited significantly at that spot. Allow Dan Russell to explain: Any solid structure has vibrational patterns.. 3. 18 0 obj The weight drop of a baseball bat is the difference between a bats length and its weight in ounces, which is the difference between a bats length and weight in ounces. If the ball didn't bounce at all then COR would be zero. Though all of this means that us amateurs dont want to have batting practice for more than 10 minutes, it does help you train. One of the definitions of the "sweet spot" is the location of the node at the barrel end of the bat. /P 20 0 R endobj Join PopSci+ to read sciences greatest stories. If you hit a baseball anywhere but at the bats so-called sweet spot, you feel all those vibrations in your hands, and about 10 swings laters youll have a bruise. /N 18 0 R Recent Research Highlights. The COR for the impact on the granite block is about
0.59 in the low speed collision here, but can be as low as 0.45 in a 100 mph
collision. << Graphs of F vs t and x vs t can also be used to
generate graphs of F vs x, showing how the force on the ball varies with its
compression. These cookies help provide information on metrics the number of visitors, bounce rate, traffic source, etc. How much force does a baseball bat generate? The outgoing speed of the ball is just the sum of the two separate parts
- the speed when the bat is at rest plus the speed when the ball is at rest. Also,. Newtons second law, which deals with the value of time, is also important in baseball. (function() { The shapes of the force vs time curves are interesting since they tell us
how the force on the ball varies with the amount of compression. Whenever an object is struck, it vibrates in response. Thats the sport that demands the most from the athletes who compete in it. The impact of a bat and a ball is still not properly
understood. Finally, if players started using bats made of a better material, the game would become dangerous as the baseball would start travelling much too fast. Both papers can be downloaded here and here. This is the location of the bat that is generally regarded as the best spot for hitting the ball. The Physics of Baseball Bat Sweet-Spot. Largest thickness - The sweet spot Bat - Ball Collision Diagrams Vball 1 = Vb Vbat 1 = V2b V bat 2 = V2a Vball = V1a Before After Your selection may affect the price of the product. /R [316 73 572 791 ] >> Understanding the sizes of bats is critical to making the best choice for your game and the best bat for you. /P 8 0 R /Matrix [0.4497 0.2446 0.02518 0.3163 0.672 0.1412 0.1845 0.08334 0.9227] Specifically, what forces and torques are exerted on the handle,
and in what directions do they act? /R [316 74 572 585 ] You can find the sweet spot by gripping the bat handle with one hand in the same place as when youre swinging. There is no set formula. With each hit, you should hear and feel the vibrations (make it easier by taping a paper cone around the knob, loosely enough that it will vibrate when the bat does). Depending on how the ball rotates, the wake may deflect. /P 4 0 R It was found, by
measuring the frequencies of lots of aluminum tubes (see photo) that the frequency is directly
proportional to the wall thickness and inversely proportional to the tube
diameter squared. The lines behind the bat, passing through the axis,
mark out angles of 5, 10, 15, 20, 25 and 30 degrees. As discussed earlier, missing the sweet spot can cause vibrations in the bat. stream
The softball bat will vibrate mainly because it either hitting or missing the sweet spot. The sweet spot classification quantifies that as a batted-ball event with a launch angle ranging from 8 to 32 degrees. A rough estimate would be that the ball rotates 1/4 revolution
while it is in the pitchers hand,
and while the hand moves forward say the last 0.2 m. If the
hand moves forward at 10 m/s =
22.4 mph then it moves 0.2 m in 0.02 sec, so the spin rate would be 12.5
rev/s or 750 rpm. the location where maximum energy is transferred to the ball. The majority of hitters take a stride when hitting, which helps the timing of their swing. 232 g bat 871 g bat 1333
g bat. Baseball bats (typically aluminum) are made up of either hardwood or metal. The bat then magnifies that force by a factor of about 100-5,000 lb or so when it collides with the ball, enough to squash the ball in half. As a
result, the fundamental and second vibration modes are both excited with about
the same amplitude. George has always been passionate about physics and its ability to explain the fundamental workings of the universe. A bat is essentially a long stick. Neither the CoP nor the 'sweet spot' maximises the velocity which the ball gains from the impact. Since it's vibrations that hurt your grip, the sweet spot is clearly the point where an impacting ball doesn't cause the bat to. Theres one where it feels good in your hands, one where the ball comes off the fastest. Preliminary In order to indicate the origin of the baseball bats problem, the following preliminary are worth mentioning. At any given time, the center of the circle can be found
by fitting a circle to three neighboring points, at say time t, and at times t
+ 0.02 s and t - 0.02 s. This gives the radius, R, of the circle, from which we
can calculate the centripetal force MV2/R as well as the force at right angles to that, given
by M (dV/dt). It minimizes vibration of the bat and results in the maximum energy delivered to the ball, meaning it travels the farthest. 21 0 obj We call the point where a baseball bat has its nodes the sweet spot. A ball takes on a different shape as it is hit because the force of the bat pushing against it is multiplied by its mass. I tossed a 12 inch softball at very low
speed and filmed the result, using two hands instead of one to increase the
spin rate and to make sure the spin axis was horizontal. Thick
walls are also needed to help prevent the walls dinting or cracking. Why does hitting a baseball on the sweet spot of a bat result in a better hit than other parts of the bat? The tubes were suspended by a length of string so
that they could vibrate for a long time without damping. PbLSZTLEE(8E@'*1mg_*eTnN*;*'V3+gm-EEetX%;Bo$ur2ss*N`.-!.kG_q6GDD'
The collision of a bat and a ball can be understood by
treating the bat as a heavy ball whose mass depends on the impact point. Strike at 12 cm Strike at 17 cm Strike at 24 cm Strike at 31 cm. Continue with Recommended Cookies, Copyright 2009-2023 real-world-physics-problems.com. Collisions.- 11.Bat Performance.- 12. Where is the Sweet Spot on a Baseball Bat? Physics; Physics questions and answers; A baseball bat has a "sweet spot" where a ball can be hit with almost effortless transmission of energy. the location which produces maximum batted ball speed. << << How is this spot and its behavior described in Mechanics? A first
guess would be at the tip of the bat since the tip travels the fastest. A knob and end loaded bat may weigh the same, for instance, but the end loaded bat will have a higher MOI. /P 17 0 R Definition. But I would expect there to be a difference.. << Adding to that is the fact that bats have narrower handles than in the past which makes the bat less sturdy and more prone to breakage. In file A, the ball spins faster than in file B, both before and after
the bounce. The shoulders reach maximum speed first, then the upper arms, then the forearm
and finally the bat. If you have two bats, each with the same weight the bat that carries more weight in the end will perform better in terms of speed. The true CoP should be measured from that point. A pitch produces a turbulent wake of air behind the ball. Softer and less dense varieties of maple that are more likely to break have been banned by Major League Baseball. In addition to the second law, we can understand how the force of the bat affects a balls motion. When one object collides with another, some of the energy from the impact goes into vibrational waves that travel through each object. Rather,
most coaches and others think in terms of wrist torque, which is probably much
too small to provide the necessary large couple near the end of the swing The
couple must come mainly from the two arms, not the wrists. The sound made by a bat can be described as a "ping". There's no stinging, no vibration and no broken bat. To increase the acceleration of the ball while it is still moving, a bat that strikes it harder will most likely accelerate faster. In principle you could also work out the
acceleration due to gravity in Sydney, but not very accurately. In general, swing weight increases
with actual weight, but swing
weight also depends on bat length and weight distribution. A bat is similar to a racquet but there are some obvious
differences. In file A, the tangential COR was surprisingly high, about 0.3. The higher the number, the heavier the bat will be, meaning it will have more mass and therefore more power when it makes contact with the ball. Take a hammer in the other hand and gently tap the bat at various places along its length. (The first person to really investigate sweet spots did so on tennis rackets.) /R [52 73 308 791 ] The 232 g bat was swung at 45
radians/sec on average (by the batter in the film). /R [316 73 572 791 ] Here you'll find information on the game of baseball, from the rules to the history. << This point, usually 5-7 inches from the barrel end, does not move when the bat is vibrating in its first (or fundamental) bending mode. These cookies ensure basic functionalities and security features of the website, anonymously. /R [316 73 572 791 ] Baseball is based on the principles of Newtons laws of motion. >> External forces are the only way to redirect the ball according to the first law of motion. The third law explains what happens to a bat when it strikes a ball. 25 0 obj A baseball bat is typically between 30-34 inches in length and can weigh anywhere from 24-30 ounces. The bat is 84 cm long, and has a mass of 849 gram. Maple bats are the most durable and have a larger sweet spot, making them ideal for power hitters. But the bat vibrates strongly for
impacts near the tip of the bat and near its center of mass. A high performance bat has a strong
trampoline effect and hence a relatively large COR. When a very light bat is swing velocity at maximum, it has little power to transfer to the ball. This makes the game easier to pick up and more exciting to watch otherwise, every hit would only be a single. The effect of the hands on the centre of percussion is
described in American Journal of Physics, , 622-630 (2004). Ball exit speed = (1 + q)V where V = bat speed at impact
point just before the impact. >> Most contact and power hitters use maple bats because the material is the strongest and has very little give, which is why they swing ash bats. Materials 2' long wooden plank (a 2"x4" plank works well) U bolt Drill Smooth rod along which the U bolt can slide (e.g., shower curtain rod) Rubber mallet Tape measure Baseball bat Procedure Drill a hole through one end of the 2"x4" plank large enough to insert the U bolt. A light bat can help with dry swing training, as it can be more effective and less strenuous. ] Because of the weight distribution, drop 8 bats tend to have a higher weight per foot than standard 8 bats. As a smaller player, you will generally be able to achieve faster bat speeds with a lighter bat. It is very surprising that no one seems to have worked this out before. I simply wanted to
know whether a hand launched ball spins at around 100 rpm or whether it could
be as high as 1000 rpm. When a ball is hit in the sweet spot, the collision of the bat and ball creates a compression wave which travels through the bat and is then transferred to the ball, causing it to travel further. The diagram below shows the swing of a wood bat filmed from a spot
above the batters head. /F 3 0 R I have done quite a bit of independent research in both areas. There are some models that include oak, but it is not as popular as maple or ash. /V 10 0 R The force on the bat can be worked out from the
velocity of the center of mass, (CM), and the torques can be worked out from
the angular acceleration. Hitting the "sweet spot" is something that baseball players strive for. There is enough physics in it to keep a PhD student busy for a few
years, but it could also be done
by any high school student as a simple introduction to the physics of baseball. However. endobj Since the CM traces out a spiral rather than a circular
path, the center of the circle moves, as the bat is swung, along the path traced out by the inner
circle of black dots. Why? /R [52 611 308 791 ] 2) Choose the right turn model As discussed earlier, a wider handle will improve bat durability and reduce the likelihood of breakage. Metal bats, on the other hand, are lighter and more forgiving, but they lack the power of iron bats. 3. My particular research interests are two-fold: the physics of the baseball-bat collision and the flight of the baseball. What have you found works for you? The
bounce was filmed at 300 fps and is played back at 30 fps in slow motion. Another simple estimate of spin rate is to throw the
ball and catch it with the other hand as soon as it is released. I simply wanted to
know whether a hand launched ball spins at around 100 rpm or whether it could
be as high as 1000 rpm. This is the online home for all things baseball. This force is required to change a 5 1/8th-ounce ball from a speed of 90 mph to a speed of 110 mph, this distorts the baseball to half its original diameter and the bat is compressed one fiftieth of its size.. Both the swinging bat and the pitched ball possess kinetic energy, which is generated by the players who swing the bat and throw the ball. Join PopSci+ to read sciences greatest stories. Its center of mass is 52.6 cm from the knob end. Interesting information on the behaviour of a ball can
be obtained by bouncing it on a force plate or on a piezo to measure force vs
time. endobj Share your thoughts with us below! This is because physics plays a major role in how the bat interacts with the ball. If you hit the ball on the "sweet spot" of the bat, you get the feeling of a solid connection with the ball. 16 0 obj For that reason, the walls of a hollow bat need to be
relatively stiff so they can vibrate at a frequency larger than 1000 Hz. The node is related to where the sweet spot is - where the bat does NOT bend or vibrate. The physics behind this phenomenon involves the transfer of energy from the bat to the ball. Each type of wood has its own unique characteristics, making it important for players to consider the type of wood when selecting a bat. Some of the numbers
change with actual speed, but the physics doesnt change. In fact, if the ball strikes the bat exactly on the ``sweet spot'' then the hitter is almost unaware of the collision. The node sweet spot differs from the center of percussion sweet spot. The end result can be a greater ball
speed off the bat, in the same way that a tennis ball bounces a lot better off
tennis strings than off a hard floor. According to Newtons third law, every action has an equal and opposite reaction. The ball bounces backward spinning counter-clockwise. Generally, heavier bats are used for power hitters, as they are able to generate more force when swinging. . >> << 3) Care for your bat Wooden baseball bats are susceptible to cold and moisture. Joe Jackson, a shoeless man, would prefer a custom-built bat known as Black Betsy. The relevant collision equations are derived in the
Physics of Baseball and Softball book (and elsewhere) and are: 1. Its moment of inertia about
an axis through its center of mass is 0.184 kg.m^2. When a ball player hits the ball with the bat, it produces an enormous amount of force on the bat in a split second the impact could mean up to 5,000 lbs of force. Every sport is governed by the laws of science physics, aerodynamics, kinematics, etc. There is a significant difference between end-load and balanced softball bats in terms of weight distribution. The following three movies show a
batter swinging three different bats as fast as possible, filmed at 25
frames/sec. The bat breaks when large amplitude vibrations reach the thin part of the handle. Performance cookies are used to understand and analyze the key performance indexes of the website which helps in delivering a better user experience for the visitors. Is swinging a bat potential or kinetic energy? Learn how to add this technique to your swing while still keeping a balanced, relaxed approach to the ball. /P 14 0 R All this means that if goal of the bats design is to provide more power and speed, it makes it more likely to to crack and shatter. Aluminum tubes are 24 to 35 inches (61 to 89 centimeters) long and 2 to 3 inches (5 to 7.6 centimeters) in diameter for making an aluminum bat. The vibration modes of a baseball bat are easily determined,3-5at least for a freely suspended bat ~e.g., one that is suspended by a light string!. A baseball bat is shaped in such a way to have a "sweet spot." The sweet spot is due to the fact that the CP and the VN coincide. The first is where the bat feels best in your hands when you hit. This equation for acceleration can , Dry ice is the name for carbon dioxide in its solid state. You also have the option to opt-out of these cookies. The stiffness of a cylinder was found to be roughly
proportional to its length x (wall thickness / diameter) squared (rather than
cubed, since the wall thickness is not negligible compared with the radius for
most of these tubes). The physics behind this phenomenon involves the transfer of energy from the bat to the ball. /I << /Filter /LZWDecode According to one study, Brazils free-tailed bats have the fastest flight speeds ever documented by flying at 160 kilometers per hour in flight.
