In George Rhoads\u2019 rolling ball sculpture, the principle of conservation of energy governs the changes in the ball\u2019s kinetic energy and relates them to changes and transfers for other types of energy associated with the ball\u2019s interactions. In this chapter, we introduce the important concept of potential energy. This will enable us to formulate the law of conservation of mechanical energy and to apply it to simple systems, making solving problems easier. In the final section on sources of energy, we will consider energy transfers and the general law of conservation of energy.
