| velocity | the speed and the direction of a moving object |
| momentum | the mass of an object multiplied by its velocity |
| force | a push or pull by one object on another |
| work | the use of a force to move an object a certain distance |
| energy | the ability to perform work or change an object |
| motion | a change in position over time |
| speed | how fast an object's position changes over time |
| formula for speed | speed = distance รท time |
| acceleration | change in velocity over time |
| momentum | product of mass times velocity |
| friction | a force that opposes the motion of one object moving past another |
| kinetic energy | energy of a moving object |
| potential energy | energy that is stored in the position or structure of an object |
| Law of Conservation of Energy | Energy cannot be created or destroyed |
