Question 8

Which of these stores elastic potential energy?

A A bucket of water hanging from a rope B A bow that has been drawn C A ball rolling down a slope D A stone resting on a wall

The right answer is the one marked above.

A bow that has been drawn. Drawing the bow changes its shape, and the work done in changing it is stored in the bow itself.

The stone and the bucket store gravitational potential energy, by position. The rolling ball is moving, so it holds kinetic energy.
