GEARS

=Gears= [image:http://i.imgur.com/qEoOqhG.png] Gears are toothed wheels that can be used to alter the size and direction of a force. The gear which has a force applied to it (is first turned) is known as the '''DRIVING''' gear. The gear which turns as a result is known as the '''DRIVEN''' gear.

Whereas the driving gear (right) turns anti-clockwise. [image:http://i.imgur.com/YknYShl.png?1] If the driving gear is larger than the driven gear the machine is a distance multiplier. Every time the driving gear is turned the driven gear turns more than once (it turns faster), but with less force.
