What force causes a ball to bounce off a wall?
When the ball hits the ground, it applies a force equal to its KE on the ground ( f=KE) and the grounds applies an equal force on the ball ( newton’s third law of motion), plus there is the elastic potential energy of the ball ( which depends on the material of the ball) which contributes to the force applied by the …
Why does a clay ball not bounce?
Some things, e.g. a lump of clay, do deform when dropped, but since they don’t significantly reassert their structure afterward, they don’t significantly bounce. Plus stuff like clay will tend to stick to some surfaces, causing resistance to any small potential bounce.
Why does a rubber ball bounce back on hitting a floor whereas a metal ball doesn t?
Rubber ball has high elasticity, therefore when it hits the wall it gets compressed and due to elasticity, it quickly returns to its original shape. While doing this it pushes back on the wall. Thus, it rebounds back. Let the mass of both the metal ball and rubber ball be m.
Why does the bouncy ball not bounce all the way back up?
Did you find that a single ball never bounced back to the height at which you released it, regardless of the ball you used? During a collision, some of the ball’s energy is converted into heat. As no energy is added to the ball, the ball bounces back with less kinetic energy and cannot reach quite the same height.
What factors affect the bounce of a ball?
The combination of the material properties of a ball (surface textures, actual materials, amount of air, hardness/ softness, and so on) affects the height of its bounce.
Why do balls bounce back up?
The force of the ball hitting the hard ground puts an equal force back onto the ball, causing it to bounce up. This happens because balls are made out of an elastic material like rubber, which means they can be dented or stretched and then return to their normal shape (think of what happens when you squeeze a balloon).
Why rubber ball bounces more than plastic ball?
TL,DR: The elasticity in the rubber ball create a potential energy when it hits the ground, making it bounce. Since rubber has a higher elastic modulus (ability to be stretchy) than other materials, it bounces higher.
How much energy is lost when a ball bounces?
For example, if a ball bounces 80\% of its height on each bounce, then the ball is losing 20\% of its energy on each bounce. The time of each bounce is about 90\% of the time of the previous bounce, the ball slows down about 10\% each bounce, and about 10\% of the linear momentum is lost at each bounce.
