Explore physics, thermodynamics, and more! What is energy? How did the idea of energy come to be? Learn about how early scientists thought about energy, kinetic versus potential energy, and how energy gets released. We discuss energy in food, fuel, bombs, and the sun. It is energy that built civilization, but will it also destroy it?
