Sometimes objects have both kinetic and potential energy. Let’s say that Child #1 is just sitting on the swing and not moving at all. Child #2 is moving backward. Her position moments ago was just like Child #3. Speaking of Child #3, he is at the very highest point of his swing.

TURN AND TALK:

Of the three children swinging, which is displaying the most kinetic energy? The most potential energy?

Explain your thinking:

Is there another point at which Child #2 or #3 will have more kinetic energy? More potential energy?
