Work, Power & Energy

Work, Power & Energy. Work. Work is the product of force and distance For a force to do work on an object, some of the force must act in the same direction as the object moves. If there is no movement, no work is done.

How does the actual mechanical advantage of a machine compare to its ideal mechanical advantage?

A nutcracker is a machine that converts the input force applied to it into a larger force capable of cracking a nut. Because it increases force, the nutcracker has a mechanical advantage greater than 1.
