Front

What is Kinetic Energy?

Back

Kinetic Energy is the energy an object has due to its motion. The faster an object moves, the more kinetic energy it has.

Front

What is Potential Energy?

Back

Potential Energy is the stored energy in an object due to its position or state. For example, a ball at the top of a hill has potential energy.

Front

What type of energy does a toaster use?

Back

A toaster uses Electric Energy to heat and toast bread.

Front

An example of Kinetic Energy is a moving car or a running dog.

Front

What is an example of Potential Energy?

Back

An example of Potential Energy is a stretched rubber band or water stored in a dam.

Front

How does energy change from one form to another?

Back

Energy can change from one form to another, such as when electric energy is converted to thermal energy in a toaster.

Front

What is the Law of Conservation of Energy?

Back

The Law of Conservation of Energy states that energy cannot be created or destroyed, only transformed from one form to another.
