Kinetic and Potential Energy

Kinetic Energy:  Kinetic Energy is the energy of movement.  The amount of Kinetic Energy a substance has depends on its state of matter.  The faster an object moves, the more Kinetic Energy it has.  There are five different types of Kinetic Energy - radiant, thermal, sound, electrical (light) and mechanical (motion).

Examples of Kinetic Energy:

• A rubber band shot from your finger.

• A moving skateboard.

• Blowing Wind.

• A ball rolling across the floor or gound.

• A wheel turning.

• A plane in flight.

• A flowing river.

• An athlete running.

Potential Energy: Potential Energy is the energy of objects not in use.  The object has the potential to have Kinetic Energy.

Examples of Potential Energy:

• When a rubber band is stretched and waiting to be released.

• A rock at the edge of a cliff, waiting to fall.

• An acorn waiting to fall from a tree.

• A car parked, waiting to be driven.

• An swimmer posed on the starting block.

• An arrow pulled back on a bow.

This roller coaster is an example of Kinetic Energy. The car is always in motion. Because it is, the car has Kinetic Energy.

This is an example of Potential Energy. The car is sitting at the top of a hill. It could go down the hill, and if it did, it would have Kinetic Energy. But, since it isn't, it has Potential Energy.
