Assertion : Work done by or against gravitational force in moving a body from one point to another is independent of the actual path followed between the two points.
Reason : This is because gravitational forces are conservative forces.

In gravitational field the work done in moving body from one point into another depends on

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 ?

Work done by gravitational force on a freely falling body ………….

The force is ………. if the work done by the force in displacing a particle from one point to another is independent of the path followed by the particle .

The work done by the Sun's gravitational force on the Earth is
