Chapter 14 Work, Power, and Machines 14.1 Work and Power Work is the product of force and distance. You can calculate work by multiplying the force exerted on the object times the distance the object moves. Work = Force x Distance; W = Fd Work is done when a force moves an object over a distance. No work is done if an object does not move or if the force you apply is not in the same direction an
