How to calculate net work physics
WebIn physics, if you want to find the change in an object’s kinetic energy, you have to consider only the work done by the net force acting on the object. In other words, you convert only the work done by the net force into kinetic energy. For example, when you play tug-of-war against your equally strong friends, you pull against each other but ... Web12 sep. 2024 · Wnet = Wgrav = − mg(yf − yi), where y is positive up. The work-energy theorem says that this equals the change in kinetic energy: − mg(yf − yi) = 1 2(v2 f − v2 …
