Power, Work, and Energy

Abstract

We begin here by discussing the notions of power and work. Subsequently,we make these ideas more precise by defining the mechanical power of a force and, from this, the work done by the force during the motion of a particle. Next, the work-energy theorem \( \dot T = {\bf F} \cdot {\bf v} \) is derived from the balance of linear momentum. It is then appropriate to discuss conservative forces, and we spend some added time discussing the potential energies of gravitational and spring forces.With these preliminaries aside, energy conservation is discussed. Finally, some examples are presented that show how all of these ideas are used.
