Explanation:

what is mechanical advantage?

• the ratio of the force produced by a machine to the force applied to it, used in assessing the performance of a machine.

what is the short form of it?

• The actual mechanical advantage (AMA) is the mechanical advantage determined by physical measurement of the input and output forces.

and also say why it is used

• Mechanical advantages allows humans to perform tasks much easier in terms of the force they need to apply, but must always obey the conservation of energy. Mechanical advantage is a measure of the ratio of output force to input force in a system, used to analyze the forces in simple machines like levers and pulleys
