Introduction
This chapter introduces Newtonâs laws of motion. A lot of classical physics is based on these laws. It was once thought that knowledge of the present state of a system and all forces acting on it would enable the complete prediction of the state of that system in the future. We will learn how to correctly identify the forces that act on a system, find the net force on a system, and apply Newtonâs laws to describe the motion that may take place.
