| Time Interval | the difference between two times |
| Displacement | a change in position having both magnitude and direction; is equal to the final position minus the initial position |
| Position-Time Graph: | a graph that can be used to determine an object's velocity and position, as well as where and when the two objects meet, by plotting the time data on a horizontal axis and the position data on a vertical axis |
| Average Velocity | the change in position divided by the time during which the change occurred; is the slope of an objects position-time graph |
| Average Speed | how fast an object is moving; is the absolute value of the slope of an objects position time graph |
| Instantaneous Velocity | a measure of motion that tells the speed and direction of an object at a specific instant in time |
