Question

If a simple machine provides an increased output force, what happens to the output distance?


It is reduced.

It remains the same.

It is increased.

Answer 1

If a simple machine provides an increased output force, the output distance is reduced. This is due to the principle of conservation of energy. In simple machines, the work input (force times distance) must equal the work output. Therefore, if the output force is increased, the distance over which that force is applied will be reduced to keep the work output the same.
