If the amount of work done by a force depends only on the initial and final positions of the object which has been moved, then such a force is called

The amount of work done by a moving body depends on the

A force is said to be conservative if work done by or agains the force depends only on initial and final positions of the body and not on the nature of path followed. A force is said to be non-conservative, if work done by or against the force in moving a body from one position to another, depeds on the path followed between these two positions. Potential energy is defined only for conservative forces. It does not exist for non-conservative forces. Read the above passage and answer the following question : (i) Give two examples, each for conservative and non-conservative forces. (ii) Potential energy does not exist for non-conservative forces. What does it imply ini day to day life ?
