... First we define the work done by a force, both in the case where the force is constant and the motion is linear, and in the general case in which the force is variable and the motion is curvilinear. Different persons or different machines may take different amounts of time to do the same amount of w ...

... 1. How much work does the gravitational force do on the block as the block travels from point P to point Q and the top of the loop. 2. If the gravitational potential energy of the block-Earth system is taken to be zero at the bottom of the loop, what is that potential energy when the block is at poi ...

... Work is the transfer of energy through motion. In order for work to take place, a force must be exerted through a distance. The amount of work done depends on two things: the amount of force exerted and the distance over which the force is applied. There are two factors to keep in mind when decidin ...
