Web4.1.1 Definition of the power and work done by a force . Suppose that a force F acts on a particle that moves with speed v. By definition: The Power developed by the force, (or the rate of work done by the force) is . If both force and velocity are expressed in Cartesian components, then WebMay 15, 2024 · Just want to complement @JacobBach's answer, the work done for the force F on the path γ is calculated as. (1) W = ∫ γ d x ⋅ F. If F can be written as as the gradient of a potential field. F = − ∇ ϕ. then (1) becomes. (2) W = ∫ γ d x ⋅ F = − ∫ γ d x ⋅ ∇ ϕ = − ∫ a b d ϕ = ϕ ( a) − ϕ ( b) Share. Cite.
