WebThe work that is done can be positive work or negative work depending on whether the force doing the work is directed opposite the object's motion or in the same direction as the object's motion. ... Thus, the external force alters the kinetic energy of the diver. (NOTE: there is another force - gravity - which changes the diver's height; but ... WebIf the object falls from that height, the same amount of work would have to be done by the force of gravity to bring it back to the Earth’s surface. If an object at a certain height has 2000 J ...

WebSep 12, 2024 · The total work done by gravity is zero [20 J + 0 J + (−20 J) = 0]. Unlike friction or other dissipative forces, described in Example \(\PageIndex{2}\), the total work done against gravity, over any closed path, is zero. Positive work is done against gravity on the upward parts of a closed path, but an equal amount of negative work is done ... WebThe challenge for students is to recognize that the force of gravity can do work on an object and thus be transformed into kinetic (or other forms of) energy. The ultimate goal …
WebJan 21, 2011 · 3. Jan 17, 2011. #12. Work done by gravity depends if you use the work-energy principle or conservation of mechanical energy. Under conservation of mechanical energy, the system is the object and the earth. Because gravity is a conservative force, it does negative work on the way up and positive work on the way down.
