This course explains clearly the concept of Work and Energy :-

1) Get a feel for Work and Energy : animation of a Turbine wheel in a hydraulic dam
2) Work-Energy Theorem: Work and kinetic energy
3) Equation for Work done :- case : animation of a robot pulling a block over a horizontal plane.
4) Work done when Force is constant
5) Work done by Spring : varying force as spring expands or compresses
6) Conservative and Non-conservative forces
7) Potential Energy concept for a Spring
8) Mass-Energy equivalence
9) Solved Problems
