... A tennis ball… Welcome back. This is the popping sound we hear when the ball is hit. Why? (In technical terms it is called an ’inelastic collision’.) If you look at the ball's speed as a vector, the vertical component of the top-spun ball's velocity is greater than the normal served ball. Tennis Physics: Anatomy of a Serve. Now as we collide with the tennis ball, energy is once again conserved. A tennis ball and basketball are dropped from a height of 1m (the tennis ball on top of the basketball). Consider the basketball to have an elastic collision with the floor. Drop the ball through the photogate.
Golf balls have a much higher coefficient of resolution because under their plastic skin resides a small, slightly harder, Super Ball. LeeH That answer works well for a nice bouncy tennis ball.
This means that the tennis ball will bounce up and away from the basketball at the same velocity as during the impact (roughly 20 mph). So by applying top spin on the ball the way tennis players do, the ball is rotating in the direction of the trajectory.
iii. Toggle navigation ... with the tennis ball on top). ii. Part of a Super Ball’s uniqueness is its ability to bounce in all directions equally. Having less energy, the ball doesn’t bounce as high. The tennis ball has a mass of 75g and the basketball has a mass of 1kg. Example 2: i. After the 32nd bounce, it's bouncing back up by less than one billionth of a foot. With the U.S. Open Finals coming up this weekend, the physics of tennis is on display for all to see. This will bend the trajectory downwards. This kinetic energy carries the racquet towards the ball. The speed of the ball immediately before and immediately after it bounces. Trial Procedure: 1. ... it must travel within a very narrow range of angles to both clear the net and bounce inside the service box. The tennis ball will bounce higher than the original point of release! When dropped separately, the tennis ball bounces to a height of 0.5m and the basketball to a height of 0.8. Under those rules a tennis ball dropped from 100 inches can bounce no higher than 58 inches, just more than half. Let’s jump back into our own shoes on the ground and conclude our observations. A very non-bouncy ball, say a lump of clay, will bounce better on some soft surface like a … Department of Physics and Astronomy. by Dr. Aaron Titus. Drop the ball from 10 different drop heights, using the video camera to record the bounce heights. If each time it bounces back up halfway, by the time the ball bounces just 12 times, it’s already bouncing back up less than one thousandth of a foot. I have an idea of making a tennis serving machine. After its 22nd bounce, it’s bouncing back up less than one millionth of a foot. Drop a ball from 4 feet. I will briefly describe what it is: The machine is configured to serve the ball at a fixed speed to the center of the left (or right) service court; Based on the rotation in 3 directions (X,Y,Z) of the ball, the machine would let the ball land in various positions in the left service court. A photogate near the floor, at a height just above the diameter of the ball, to measure the ball’s speed.
Drop the tennis ball from rest from the starting height (H) 2. When it hits the ball, the kinetic energy becomes three different types of energy. Analysis of Double Ball Drop The two slightly separated balls dropped from the same height are seen by a ground observer to approach the surface with velocity v. A ground observer sees the larger ball hit and bounce up with velocity v while the smaller one still approaches. The first type is sound energy.
