Supernovae - The Answer
Supernovae - The Answer
The tennis ball will bounce up to a height much higher than from where it started.
This phenomenon occurs because of Conservation of Momentum. This law states that in a system of moving bodies which are not affected by any external forces, the total momentum in the system remains unchanged during interactions between the objects. Simply stated, the total momentum of two objects, before and after a collision will remain unchanged.
Example: If you have ever played pool, recall that the cue ball is made to collide with the other balls on the table. The white ball will stop short when it collides head-on with another ball at rest. The momentum is transferred from the cue ball to the second ball at the point of collision.
