Explain the energy of moving objects with an activity.

Explanation

1) Consider a metal ball and a hollow plastic block which are kept on a table side by side.
2) Now, suppose that the ball is separated from the block and brought to one end of the table and pushed to roll on the table with speed 'v'.
3) We may notice that, the ball hits the plastic block and displaces it from point A to B.
4) Thus a moving ball is more energetic than the ball at rest.
5) We can conclude that a body possesses more energy when it is moving than when it is at rest.
