| Effort | The action of applying a force. |
| Force | The application of a push or pull. Force is represented mathematically as "F". |
| Gram | A basic unit in the metric system used to measure mass. Grams are represented mathematically as "g". |
| Load | An object(s) moved by force. |
| Mass | The quantity of matter in a body, object or substance. |
| Meter | A basic metric unit of length used to measure distance. (m) |
| Newton | A unit of force, which is represented mathematically as "N". |
| Spring Scale | A scientific tool that measures force between newtons. (N) |
| Joule | A unit in the metric system used to measure work. "J" . They equal newton-meter. (N-m) |
| Work (W) | A measure of the distance (d) over which a force (f) is applied. |
| Formula for Work | Work = Force x distance (W= Fd) |
| Effort Arm | The part of a simple machine that supports the effort (i.e. where force is applied) |
| Fixed Pully | A simple machine that is attached to a surface and uses a stationary grooved wheel through which a rope, belt, chain , etc. runs. |
| Load Arm | The part of a simple machine that supports a load (i.e. where the load is attached) |
| Simple Machine | One of 6 devices that make work feel easier. |
| The 6 Simple Machines | Fixed Pully, Lever, Inclined Plane, Wedge, Screw, and Wheel and Axle |
| Fulcrum | The component of a lever which supports the beam and upon which the beam turns. |
| Lever | A simple machine consisting of a beam that turns on a fixed point, called the fulcrum. |
| Inclined Plane | A simple machine consisting of a sloped surface. |
| Machine | A mechanical device that changes the application of a force required to move a load. |
