Examples of Potential Energy
Kinetic Energy • Kinetic energy- the energy of a moving object • Have you seen any objects in motion today?
Examples of Kinetic Energy
Changing Energy • Sometimes the type of energy in an object can swap back and forth. • Think of a roller coaster!
Examples of Changing Energy
Rubber Band Potential Energy • A rubber band that is stretched has potential energy. Kinetic Energy • When the rubber band is let go and flies through the air, it has kinetic energy.
Candle Potential Energy Kinetic Energy • An unlit candle sitting on a table has potential energy. • When the candle is lit and burning, it has kinetic energy.
