Potential Energy • Potential Energy is energy due to an object’s position. • Ex) a stretched rubber band • A book on a shelf • A coaster at the top • And the list goes on…
Calculate it! • Potential Energy = mgh • m = mass in kilograms • g = gravity (9.8m/s2) • h = height in meters
Practice • A skateboarder who weighs 50kg is perched at the top of a half pipe. The half pipe is 5m tall. What is the skateboarders potential energy? PE = 50kg*10m/s2*5m PE = 2,500 Joules
