How does the pong ball bounce?
Balls, including ping pong balls, bounce after they hit a solid surface because an equal and opposite force from the surface pushes them back upward. Instead of all of the energy pushing the ball back upward, some is spent deforming the ball, and then pushing it back to its original shape.
How does bouncing balls work physics?
When a bouncing ball falls, it initially gains speed or kinetic energy—the energy of motion. The ball slows down, deforms temporarily and shoots back up. The air in the ball acts like a spring—it gets compressed and expands again. During the collision, some of the ball’s energy is converted into heat.
How do you calculate bounce height?
Between the first and second bounces, the height can be expressed as h = 140 − 16(t − 6.49)2, 3.54 ≤ t < 9.45. The 6.49 is when the highest point is achieved (halfway between the two bounces), and the 9.45 seconds is derived from adding 3.54 seconds to the time between the first and second bounces.
What should the bounce be on a pong ball?
Depending on where the ball hits the paddle, it should bounce off in an angle of between -90 and 90 degrees, where the middle of the pad would give 0 degrees, and the extremities on each side should give -90 or 90 respectively. (The numbers are just for reference.)
How to calculate the speed of a ball in Pong?
I notice you have velocity and velocity2; it might make things easier to use a 2D vector for velocity, like you do for position. To calculate the speed in the X and Y directions, just multiply your total speed by the cos (for the horizontal component) and sin (for the vertical component) of the angle.
How does the height of the drop affect the bounce?
The procedure also involved observing how the height from which a ball is dropped affects its bounce. A ball’s gravitational potential energy is proportional to its height. The air pressure affects how high the ball will bounce back up. Our group needed to experiment to prove this.
How is the bounce coefficient of a tennis ball determined?
In the experiment, “Bounce Height vs. Drop Height”, we determined the bounce coefficients of a tennis ball, ping pong ball, and a golf ball. The procedure also involved observing how the height from which a ball is dropped affects its bounce. A ball’s gravitational potential energy is proportional to its height.
