Question

A force F is applied to the see saw. F is applied a distance 2d from the pivot point, and the black box is a distance d from the pivot point (not to scale). Compare the work done by gravity and the work done by the force F when the see saw is displaced through the angle (i.e.: Is the work done by gravity greater than, equal to, or less than the work done by the force F).

Compare the work done by gravity and the work done by the force F when the see saw is displaced through the angle (i.e.: Is the work done by gravity greater than, equal to, or less than the work done by the force F).

Explanation / Answer

here work done by F is positive and workdone by gravity is vegative.

so work done by gravity < workdone by force
