| Slope | Refers to the steepness of a line on a graph. |
| Acceleration | The rate at which velocity changes over time. |
| Deceleration | Refers only to the slowing down of an object. |
| Instantaneous speed | The rate of motion at any given moment in time. |
| Reference point | A beginning or starting place. |
| Velocity | The speed of an object in a particular direction. |
| Speed | The rate at which an object changes position. |
