  1. Simple Machines

  2. Machine • Machine- A tool used to make work easier.

  3. Simple Machine • Simple Machine- Simple tools used to make work easier.

  4. Compound Machine • Compound Machine- Two or more simple machines working together to make work easier.

  5. Work • Work- A force acting on an object to move it across a distance.

  6. 7 types of simple machines

  7. Inclined Plane • Incline Plane- A flat surface that is slanted to help move objects over a distance.

  8. Wedge • Wedge- The pointed edge of an inclined plane. Used to push things apart.

  9. Screw • Screw- An inclined plane wrapped around a cylinder.

  10. Lever • Lever- An arm that pivots (turns) against a fulcrum.

  11. Wheel and Axle • Wheel and Axle- The rotation of a lever against a point, moving an object across a distance. The wheel turns the axle.

  12. Pulley • Pulley- The use of a wheel to rotate a rope or cord. The cord wraps around the wheel, and as the wheel rotates, the rope move in either direction.

  13. Gear • Gear- Two toothed wheels that fit together so that one moves the other.
