Which statement about simple machines is correct? (1 point)

Question

Simple machines do not change the amount of work done

Simple machines always increase the distance that force is applied to do work.

Simple machines always reduce the force needed to move a load.

Simple machines increase the amount of work done.

Answer 1

The correct statement about simple machines is:

Simple machines do not change the amount of work done.

This is because while simple machines can change the way work is done (by altering the direction of force or the distance over which a force is applied), the total amount of work (force multiplied by distance) remains the same, assuming there is no loss due to friction or other efficiencies.
