Question

Do machines decrease the amount of work done?

Answer 1

A machine does not decrease the amount of work that is done. Instead, a machine changes the way in which work is done. Recall that work is the use of force to move an object. If, for example, you have to lift a heavy box, you can use a ramp to make the work easier.

Machines apply force over a greater distance, so less force is needed. ... < 1 - reduces output force and increases the distance the object moves.
