| Motion | When an object's distance from another is changing. |
| Reference Point | A place or object used for comparison to determine if an object is in motion. |
| Speed | The distance an object travels in a unit of time. |
| Velocity | Speed in a given direction. |
| Acceleration | The rate at which velocity changes. |
| Initial Velocity | The rate at which an object is moving at the beginning of a unit of time. (Vi) |
| Final Velocity | The rate at which an object is moving at the end of a unit of time. (Vf) |
| S=d/t | The formula for calculating speed or velocity. |
| Final velocity minus Initial velocity divided by time | The formula for calculating acceleration |
| Appears on the X axis of a speed or acceleration graph. | Time |
| Appears on the Y axis of a speed graph. | Distance |
| Appears on the Y axis of an acceleration graph. | Speed |
