| an object's change in position; how far an object is from where it started | displacement |
| physical quantity that has both magnitude and direction; has a number, a unit, and a direction | vector |
| rate at which an object's position changes | velocity |
| the total displacement of an object divided by the total time it takes for the displacement to occur | average velocity |
