Question

When the first ball in a Newton's cradle is pulled back and released, it causes the final ball to move. What does this example of mechanical energy show?

Answer 1

Answer:

You witness this conservation of momentum as the last ball swings into the air with nearly the same momentum as the first ball. Thus, if two balls are lifted into the air on one end of the device and released, then two balls on the opposite end will swing in response.
