Students learn to define and recognize the six simple machines: the inclined plane, the wedge, the screw, the lever, the wheel and axle, and the pulley. Real life situations demonstrate the function and purpose of each machine. Students learn the definition of work and the relationship between force and distance.

Real-life situations demonstrate the function and purpose of each machine. Youll also learn the definition of work and the relationship between force and distance.

A simple machine is a mechanical device that changes the direction or magnitude of a force. In general, they can be defined as the simplest mechanisms that use mechanical advantage (also called leverage) to multiply force. Usually the term refers to the six classical simple machines that were defined by Renaissance scientists:

Lever

Wheel and axle

Pulley

Inclined plane
