Efficiency Energy When we get work from a machine or a body that work is smaller than the energy supplied to that machine or body…

Power is a change in energy with respect to time. One way to add energy to a system is to apply force in the direction…

Unit of power Power is the rate at which work is done or energy is transferred in a unit of time. It is increased if…

Power is the time rate of doing work of an agent and it is measured by work done in unit time. Whether displacement of a…

Energy of Simple Harmonic Motion Simple harmonic motion is any periodic, repetitive motion where a restoring force is applied that is proportional to the displacement,…

Application of principle of conservation of mechanical energy In case of collision between two trains energy conversion of similar type takes place [Fig. a]. Before…

Application of the Principle of Conservation of Energy When two palms are rubbed together, they become warm; here mechanical energy is converted into heat energy.…
