WebIn the case of a variable force, integration is necessary to calculate the work done. The work done by a constant force of magnitude F, as we know, that displaces an object by Δx can be given asL: W = F.Δx. In the case of a variable force, work is calculated with the … WebThe work done by a constant force of magnitude F on a point that moves a displacement d in the direction of the force is the product: W = Fd. Integration approach can be used …
WebApr 13, 2024 · Work done by frictional and viscous force is always negative. (b) Work done by a variable force. Suppose a force F is not constant but depends on the position vector r of the body, then the work done by the force F in moving the body from a position r1 to a position r2 is given by. Energy WebApr 6, 2024 · The right-hand side of this equation denotes work done. Hence we get, ΔK = W. The above equation is the proof of the work-energy theorem for the variable force. …
