Answer 2

here

The resistance, or the downwards force, is the weight of the person you are trying to lift is at one end. The work, force applied to the lever, is the person sitting on the other end of the seesaw.

The mechanical advantage of using a long lever to lift a heavy weight is

apparent: much less force is need to lift a heavy object with a lever if the distance

from the pivot point is large compared to the distance of the heavy object from the

pivot point
