Web5 dec. 2024 · Now, work done due to gravity = –mgs = –5(9.8) (2.5) = –122.5 J Therefore, net work done on the block = work done by T + work done by mg = 147.5+ (–122.5) = 25 J. Point of application of force also plays a major role. Zero work is done by a force in following cases: -If the point of application of force is not changed in WebWhen a force does work on an object, energy is exchanged between the object and its surroundings. Power The rate at which energy is exchanged is called power. Power …
