An … WebApr 4, 2014 · Work is defined as a force applied during some distance. From these definitions, it is clear that the duration of the force does not directly impact how much energy is required. For instance, Earth exerts a force of gravity over the Moon. This force persists and the Moon does not get closer (at least not significantly for this purpose).

Webgravity, also called gravitation, in mechanics, the universal force of attraction acting between all matter. It is by far the weakest known force in nature and thus plays no role in determining the internal properties of everyday matter. On the other hand, through its long reach and universal action, it controls the trajectories of bodies in the solar system and … http://www.qrg.northwestern.edu/projects/vss/docs/space-environment/3-mass-and-distance-affects-gravity.html
