WebThe work done depends on the type of energy conversion of the bodies when a force is applied. That means, when we apply force on the body at rest, the conversion of potential to kinetic energy occurs – which accelerates the body to move in the direction of applied force.Likewise, when the surface exerts sliding friction on the moving body, its kinetic … WebCheck the answer to see if it is reasonable. Once you have solved a problem, reexamine the forms of work and energy to see if you have set up the conservation of energy equation correctly. For example, work done against friction should be negative, potential energy at the bottom of a hill should be less than that at the top, and so on.
