Work is said to be done when the applied force is able to produce displacement.The ability of doing the work is measured in terms of energy. Mechanical energy is of two types. Potential energy is the energy possessed by the body by virtue of its position and kinetic energy is the energy possessed by the body by virtue of its motion. Power is the ability of doing the work quickly. In the video lessons all this topics are explained in detail with short videos. Some of examples and problems are solved in detailed derivations. Your further suggestions to make them better are always welcome.
Following are the video lessons.
