Energy is neither created nor destroyed: it is only transformed. There are many different forms of energy, including kinetic energy (the energy of motion), potential energy (energy that is considered stored because of an object’s position), mechanical energy (energy that performs work), and thermal (heat) energy. Kinetic and potential energy are often paired together in simple demonstrations, like dropping a book, jumping on a trampoline, or building cool machines like rubber band cars.
Learn how to make a rubber band car.
