Energy • Energy- the ability to do work • You have to have energy to do everything you do! • The more energy you have, the more you can do. • Moving objects have energy (duh) and still objects have energy!
Potential Energy • Potential energy- the energy stored in an object (still objects) • Have you seen any objects today that were storing energy?
Kinetic Energy • Kinetic energy- the energy of a moving object • Have you seen any objects in motion today?
Changing Energy • Sometimes the type of energy in an object can swap back and forth. • Think of a roller coaster!
