What you need to know
- Kinetic energy is the energy an object has because it is moving.
- Kinetic energy equals one half times mass times speed squared.
- Doubling the speed gives four times the kinetic energy, because speed is squared.
- The equation can be rearranged to find mass or speed from a known energy.
