What is the best way to explain the loss of kinetic energy of the ball during the collision.
A hard rubber ball is dropped from rest.
It falls to the floor and bounces back up to almost its initial height.

A rubber ball is dropped from rest at a fixed height.
What is the best way to explain the loss of kinetic energy of the ball during the collision.
A rubber ball is dropped from rest at a fixed height.
So in this example the positive direction the away from the detector direction is downward.
Explain the answer.
Normally we don t think about the physics of bouncing balls too much as it s fairly obvious what is happening the ball basically rebounds off a surface at a speed proportional to how fast it is thrown.
Energy was required to deform the ball s shape during the collision with the floor.
Almost everybody at some point in their lives has bounced a rubber ball against the wall or floor and observed its motion.
At what height above the ground do the balls collide.
When a rubber ball dropped from rest bounces off the floor its direction of motion is reversed becaue a energy of the ball is conserved b momentum of the ball c the floor exerts a force on the ball that stops its fall and then drives it upward d the floor is in the way and the ball has to keep moving e non of the above.
Simultaneously a second rubber ball at height h directly above the first ball is dropped from rest.
Assume the heavier ball reaches the floor first and bounces elastically.
It bounces off a hard floor and rebounds upward but it only reaches 90 of its original fixed height.
It bounces off a hard floor and rebounds upward but it only reaches 90 of its original fixed height.
From what height was the ball dropped if the magnitude of the ball s momentum is 0 760 kg.
A hard rubber ball is dropped from rest.
When the balls are released the lighter ball with mass m is directly above the heavier ball with mass m.
A rubber ball with a mass of 0 160 kg is dropped from rest.
A motion detector is mounted on the ceiling directly above the ball facing down.
How high does the ball bounce.
A rubber ball is shot straight up from the ground with speed v0.
