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.
