The transference of energy may take place as work if the system and surroundings have different pressures. For e.g., suppose a gaseous system is enclosed in a cylinder fitted with a movable piston. If pressure of the system is higher, the piston will be pushed up until the pres..

During high tide, when the level of water in the sea is high, sea-water flows into the reservoir of the barrage and turns the turbines. The turbines then turn the generator shaft to produce electricity. During low tide, the sea-water stored in the barrage reservoir is allowed to flow out into..

Summary - The essential conditions to be satisfied for work to be done are: Some force must act on the object The point of application of force must move in the direction of force W = F x S SI unit of work is joule Energy is the capacity to do work The two types o..

Introduction - For a layman the term 'work' implies any activity resulting in muscular or mental exertion. In physics, however, the term has a different meaning. It represents a physical quanti..
