Unit 3: Energy and Society

Energy is the ability to do work or cause change. It comes in various forms such as kinetic energy (energy of motion), potential energy (stored energy), thermal energy (heat), and more. Think of energy like a superhero's power — it can transform from one form to another and is always conserved, meaning it cannot be created or destroyed, only transferred or converted. Whether it's the energy in a moving car, the heat from a campfire, or the electricity powering your devices, energy is what makes things happen in the universe.
