What forms of energy do gears use? there has to be 2 plz

Gears work on the principle of mechanical advantage .

Explanation:

Gears are usually used for two purposes increasing speed and force. Gears work on  the principle of mechanical advantage.

Mechanical advantage of a system is defined as the ratio of output force to the input force.For gears we have special term called gear ratio.

As the gears rotate with a angular velocity we say that gears operate with rotation energy. These are usually connected to a big system where electrical energy is converted into mechanical i.e. rotational energy. So the gears form up a connection series called gear train to increase or decrease the speed or any other requirement.

yup its correct its: c) b b
