What's the difference between kinetic and potential energy?
1. Potential energy is more powerful than kinetic energy.
2. Potential energy is another word for mechanical energy. Kinetic energy is stored energy.
3. Potential energy is stored energy (energy that is not being used right now). Kinetic energy is another word for mechanical energy. It's the energy of things in motion.
