Chapter 8 Energy and Power
Energy is perhaps the most important property of every physical system. In this chapter, first, I will introduce energy due to motion, also called kinetic energy. Then, we will study interaction by which energy from one body may be transferred to another body. The energy transfer due to force betwen bodies is called Work. Conservative interactions allow us to introduce a concept of potential energy. We will look at potential energies of some common forces and discuss conservation of energy. We will also study energy in collisions.
