Next: Newton's First Law Up: Main physics index Previous: Force
In this section we introduce the concept of force. We discuss Newton's laws,
which describe the way a body responds to a net force. We discuss frictional
forces and the way they can be mathematically represented. We study several
applications of Newton's laws.
Idea: Force is the cause of motion in classical mechanics. Classical mechanics deals with systems of size 10- 10 m (atomic dimensions) and velocity 3.0 x 108 m/s (the speed of light).
