| Speed | rate of change in position |
| Instantaneous Speed | rate of motion at any given instant |
| Constant Speed | speed that doesn't vary |
| Average Speed | the toatal distance traveled by the total time of travel |
| Speed = | distance/time |
| Distance = | speed * time |
| Time = | distance/speed |
| Velocity | speed and direction of an object |
| acceleration | rate of change in velocity |
| Acceleration formula | A=Final velocity - Initial velocity / time |
| Force | A push or pull |
| Balanced Forces | Forces that are equal in size and opposite in direction |
| Net Force | the resulting velocity of an object when multiple forces are applied to it |
| Inertia | tendency of an object to resist and change in its motion |
| Newton's 1st Law of Motion | An object moving at a constant velocity keeps moving at that velocity unless a net force acts on it |
| Friction | The force that opposes motion between two surfaces that are touching each other |
| Gravity | The attracting force exerted by every other object |
