| Energy | The ability to do work or cause change |
| Kinetic Energy | The energy of motion |
| Potential Energy | Stored energy of an object due to its position, condition, or chemical composition. |
| Mechanical Energy | The kinetic energy plus the potential energy due to position. |
| Law of Conservation of Energy | Energy can be neither created nor destroyed, only transformed. |
| Gravitational Potential Energy | The energy of an object due to its position off the ground |
| Position | The location of an object |
| Reference Point | A location to which you compare other locations. |
| Speed | A measure of how far something moves in a given amount of time. |
| Velocity | Speed in a certain direction |
| Vector | A quantity with both size and direction |
| Motion | A change in position over time. |
| Average Speed | A way to calculate the speed of an object that may not always be moving at a constant speed. |
| Acceleration | The rate at which velocity changes |
| Centripetal Acceleration | Acceleration in a circular motion |
