Physics work and power problems
WebbThe work done on the lawn mower is W = F → · d → = F d cos θ, which the figure also illustrates as the horizontal component of the force times the magnitude of the displacement. Figure 7.3 Work done by a constant force. (a) A person pushes a lawn mower with a constant force. WebbThe general formula for work and for determining the amount of work that is done on an object is: W = F × D × cos (Θ) where W is the amount of work, F is the vector of force, D is the magnitude of displacement, and Θ is the angle between the vector of force and the vector of displacement.
