Question 44

A child slides down a rough playground slide. They start from rest at the top of the slide and reach the bottom with less kinetic energy than the gravitational potential energy they had at the start.

What happens to this 'lost' energy?

A

It is converted into chemical energy in the child's body.

B

It is converted into internal (heat) energy of the slide and the child, and sound.

C

It is destroyed by the force of friction between the child and the slide.

D

It is destroyed as the child moves down the slide.
