Summary on Work-Energy of Particles

This video goes over the main concepts of work-energy for a particle and a system of particles.

0:00 Introduction
1:15 Work - defined as displacement along direction of force.
1:57 Consider a particle traveling a horizontal path
3:44 Later on we find out this is a conservative force
4:44 Spring force is newish
5:58 Forces that do no work
6:21 What happened to Newton's second law?
7:54 Power-Rate of Doing Work
9:32 Gravitational Forces and Spring forces are conservative
10:39 Work Energy
