| Newton’s First Law | Objects in motion tend to stay in motion and objects at rest tend to stay at rest unless acted upon by an unbalanced force. |
| Newton’s Second Law | Force equals mass times acceleration (F = ma). |
| Newton’s Third Law | For every action there is an equal and opposite reaction |
| Inertia | the tendency of an object to resist changes in its state of motion |
| Acceleration | a change in velocity (changing speed, direction or both) |
| Velocity | The rate of change of a position along a straight line with respect to time |
| Force | push or pull |
| Mass | The amount of matter in something. It is also a measure of the body's inertia |
| Weight | the force acting on the object due to gravity |
| Friction | the resistance of motion when one object rubs against another |
| Kinetic Energy | energy of motion |
| Potential Energy | stored energy |
