How does Energy Change Form?

Mr. Leslie’s Class

Potential Energy• Potential Energy- is energy that is stored in

an object.– It is due to the object’s position or to

substances the object is made of. – Example: A diver standing on the diving board

has potential energy because she is above Earth’s surface and will fall due to the force of Earth’s gravity.

• Energy that an object has because it is moving is kinetic energy.

• Energy often changes back and forth between potential and kinetic energy.
