Potential and kinetic Energy
Potential Energy It is the energy that is stored and held in readiness PE – the object does not move Potential energy has the ABILITY to do work
Examples of Potential Energy A stretched rubber band A skier ABOUT to go down the hill A diver on the board.
Kinetic Energy Energy of motion Objects that are in motion are doing work which means they have kinetic energy
Examples of Kinetic Energy Bowling Dog running Moving water
