Kinetic and potential energy
Kinetic energy is the energy of motion: the faster something moves, the more kinetic energy it has, and the more mass it has, the more kinetic energy it has too, a heavy truck moving at the same speed as a bicycle has far more kinetic energy. Potential energy is stored energy, like a ball held up high or a stretched rubber band, ready to become motion when released, and for objects that interact at a distance, like two magnets or two charged objects, the amount of potential energy stored also depends on how far apart they are.
