| Momentum | the product of mass and velocity |
| Impulse | equal to the CHANGE in momentum |
| Kinetic energy (KE) | the energy of motion |
| Potential energy (PE) | the energy of position |
| Mechcanical energy | KE + PE |
| Power | the rate at which work is performed or energy is consumed |
| Work | product of force and distance |
| Machine | device that either multiples a force or changes the direction of the force |
| Efficiency | work done divided by the energy used to do the work |
| Momenum conserved | all collisions |
| Momentum and energy conserved | elastic collisions |
| Momentum conserved, mechanical energy is not | inelastic collisions |
| Energy of motion | kinetic energy |
