Final answer:
The mechanical advantage of a simple machine refers to the ratio of output force to input force, showcasing how force can be magnified through machines while trading off distance.
Explanation:
Mechanical Advantage:
Simple machines are tools that can magnify or enhance the force applied to them, often at the expense of the distance over which the force is applied. The mechanical advantage of a machine is the ratio of the output force it generates to the input force applied to it. For example, a lever's mechanical advantage is determined by the ratio of the lengths of its two arms.
