Energy is the ability to do work. This basically means that if we didn’t have energy we wouldn’t even be able to nod our heads! That’s why energy is important. There are two types of energy there is potential energy, and there is kinetic energy. Potential energy is stored energy which is like when you are riding up a roller Coster and before you get to the top of it. It’s when its going up. Once you get to the top it stops and turns into kinetic energy which is the energy of motion. Kinetic energy occurs when you are going down the big hill of the roller coaster. There are other types of energy but these are the most important ones.
