Simple Machines Physics

Simple machines are devices that can be used to multiply or augment a force that we apply often at the expense of a distance through which we apply the force. The word for “machine” comes from the Greek word meaning “to help make things easier.” Levers, gears, pulleys, wedges, and screws are some examples of machines.

Physics for Kids: Simple Machines Ducksters

Simple machines were first discovered and described by Greek philosopher Archimedes. The Egyptians likely used the inclined plane to help build the pyramids. Using ramps would have made getting the large stones to the top much easier. Galileo was the first to work out a working mathematical theory on how simple machines worked.

A lever is a stick or plane that rotates on a central point called a fulcrum. See-saws, tongs, scissors and nail clippers are all examples of this simple machine. The lever and fulcrum let you exert greater force on objects than you could with your muscles alone;
