Work and Energy

Until now we used terms like velocity, acceleration, force etc. which mean more or less the same thing to a physicist and a layman. The term work is an exception. In ordinary conversation the word may mean a wide variety of activities, but in the domain of physics, its use is far more restricted. The concept of energy is closely associated with that of work. Be it a physicist or a common man, everyone has an awareness of energy and what it truly means. We shall mostly be dealing with Mechanical Energy which is further classified into two types: Kinetic Energy and Potential Energy. Through our video lectures on Definition of Work, Work Done by a Varying Force, Concept of Energy and Derivation of Work-Energy theorem, Principle of Conservation of Mechanical energy and Some Applications, Equivalence of Mass and energy, Conservative and Non-Conservative Forces, Potential Energy Function, Principle of Conservation of Mechanical Energy and Some Applications etc. we elaborately illustrated the topic for a crystal clear understanding and application.
