| mechanical energy | sum of potential and kinetic energy |
| gravitational poetential energy increases as | height increases |
| kinetic energy changes only if | velocity changes |
| an electron volt (eV) is a unit of enrgy equal to | 1.6 x 10^-19 Joules |
| work = | energy |
| power is also called the | rate of change of energy |
| power is measured in | Watts |
| law of conservation of energy | energy is neither created or destroyed |
