The Gear is another simple machine that I will describe. The gears looks like a wheel, but has kinks in it.
Gears are wheels with teeth. You can use gears to slow
things down or speed them up, to change direction, or to control several things at once. The gears, when placed together,
have to be fitted into the teeth. Each gear in a series reverses the direction of rotation of the previous gear. The smaller
gear, will always turn faster than the larger gear and in doing so, turn more rounds. You can find gears near the back wheels
of cars and motorcycles.
