The two main types of energy are kinetic energy and potential energy. These energy types are both conserved, which means that neither energy type is created or destroyed. Instead, kinetic and potential energies are transformed into each other.
Kinetic energy is the energy of motion. Every object in the universe that moves has kinetic energy. One example of kinetic energy is electricity. Potential energy is the amount of work that an object does. In other words, it's the energy potential of an object. Kinetic and potential energies can transform into each other during everyday events. For example, while on a roller coaster, the riders have potential energy at the top of the hills and the potential energy is transformed into kinetic energy to move the coaster down the hills. The two types of energy continue to transform into each other throughout the ride.
