Unit 10 · Electric Force, Field, and Potential

Chapter 10.3

Electric Potential Energy, Potential, and the Energy of a Moving Charge

Push two like charges together and you can let go with nothing moving, yet the energy you spent has not vanished. It is stored in the arrangement, and a map of it predicts every motion.
