S3 Energy and Work
Motivation
To describe the changing world around us, we must describe its state. Energy is one of the key tools that allows us to do this. In this section we explore the concept of energy: its definition, its conservation and its utility in problem solving.Objectives
By the end of this section you should:
- know how work, kinetic energy and potential energy are defined
- understand why a potential energy can only be defined for a conservative force
- be able to use conservation of energy to solve simple problems
