No work done physics
WebThe amount of work a force does is directly proportional to how far that force moves an object. The 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 ... WebThe formula for work done when the force is applied at an angle to the direction of motion is given by, W = F S c o s θ When there will be no component of force, parallel to the …
