Gears

Gears are small, toothed TECHNIC elements used to transfer kinetic energy, and in many cases change speed. All gears have an axle hole in the center, and many have connector holes on the edges. Different combinations of gears changes speed in different ways. For example, A small gear connected to the power source next to a larger gear would result in the large gear going slower. They are often combined with Power Functions elements to increase playability.
