| Simple Machines | these allow us to move things more easily by magnifying our efforts |
| Axle | a rod on which wheels rotate |
| Wheel | considered a simple machine, must rotate on a rod called an axle |
| Fulcrum | wheel & axle move around this fixed turning point |
| Turning Power | what you get when you turn the wheel further than you need to |
| Inclined Plane | an inclined surface; slope; slant |
| Work | the effort exerted over a certain distance |
| Effort | The amount of physical activity you exert to get work done |
| Distance | an inclined plane increases this, lowering the effort |
| Screw | threads on this are like a long ramp, wrapped around a piece of metal |
| Ramp | this is a basic example of a simple machine called the inclined plane |
