| Frame of Reference | A point or background used for comparison |
| Relative Motion | Apparent change in position compared to someting another object |
| Speed | The rate at which distance is traveled in a given time |
| Velocity | Speed in a given direction |
| Vector | A quantity that has magnitude and direction |
| Average Speed | A total distance traveled in a total time, during which the there may have been various speeds |
| Constant Speed | A steady rate of change in position |
| Inertia | Resistance to change in motion |
| Momentum | A property that is calculated by taking an object's mass x its velocity |
| Friction | A force that exists between any two objects that are in contact |
| Acceleration | Any change in velocity per given amount of time |
| Magnitude | Speed is this part of the velocity vector |
| Direct Relationship | Factor A increases and causes an increase in Factor B |
| Inverse Relationship | Factor A increases and causes an decrease in Factor B |
| Friction | A force that is present when particles or surfaces are in contact |
| Potential Energy | Stored energy due to an object's position |
| Kinetic Energy | Energy of motion |
| Elastic Potential | A stretched rubber band or spring would an example of this specific type of potential energy |
| Gravitational Potential | A specific type of potential energy an object has due to its height and ability to fall |
