Kinetic Energy: the energy of motion
This ball has kinetic energy because it is moving.
The word “kinetic” in English comes from the Greek word kinetikos (moving).
Look around you right now. List three or more things with kinetic energy and compare your answers with someone else in the class.
Potential Energy:
the energy of relative position or shape.
This ball has potential energy. It’s not moving right now, but it could if the girl let go of it. The ball’s position relative to the Earth has given it potential energy.
Potential energy is all around you too, but it might be a bit harder to spot. Do you see anything with potential energy around you? Anything that is inflated? Propped up? Hanging? Usually these are examples of things that are not moving but could if something happened. They have the potential to move.
List three or more things with potential energy.
