| Term | Definition |
| Simple Machine | A machine that does work with only one movement |
| Wheel and Axle | a simple machine consisting of two circular objects of different sizes; the wheel is the larger of the two circular objects |
| Pulley | Pulley A simple machine that consists of a rope that fits into a groove in a wheel. Used to lift things. |
| Inclined Plane | A flat surface set at an angle or an incline with no moving parts that is able to lift objects by pushing or pulling the load. |
| Wedge | An object that comes to a thin edge and is used for splitting or for cutting. Is used by being driven into something. |
| Screw | An inclined plane wrapped around a cylinder. Used to put things together |
| Lever | a simple machine that consists of a bar that pivots at a fixed point called a |
| What is the purpose of a pulley? | The purpose of a pulley is to make lifting heavy objects easier by distributing the force. |
| When you add multiple pulleys together, what happens to the amount of force needed? | The amount of force needed is reduced because the weight of the object/load is divided by the number of pulleys |
| To use the least amount of force while using a pulley you should... | Use several pulleys together |
| What is the relationship between the number of pulleys and the weight of an object/load? | The weight is divided by the number of pulleys |
| The disadvantage to using a lever | Force must be applied over a longer distance. |
| Examples of levers: | wrench, seesaw |
| Examples of wheel and axles: | bicycle, tires |
| Examples of a wedge: | saw, scissors, |
| Gears | wheels with teeth that can either increase the speed of a machine or its force, but not both at the same time |
| Examples of gears: | clock, lock on a safe |
| Examples of screws: | Camera Tripod, things that put objects together |
| Examples of pulleys: | Water well/wishing well |
| Fulcrum | The fixed point that a lever rotates around |
| mechanical advantage | Ratio of the force exerted by a machine to the force applied to the machine. |
