Question

what happens to the energy when a ball hits the ground and does not bounce? it is converted into thermal energy. it remains as kinetic energy. it is destroyed. it is converted into potential energy.

Explanation:

According to the law of conservation of energy, energy cannot be created or destroyed. When the ball hits the ground and doesn't bounce, its kinetic energy (from motion) is not retained as kinetic energy (since it stops moving). It also doesn't convert to potential energy (as there's no height gain). The energy is converted into other forms, mainly thermal energy due to friction and deformation (heating up the ball and ground slightly).

Answer:

It is converted into thermal energy.
