Motion: When a person changes its position with respect to its surroundings is called motion.

In motion, when a body moves from one place to another place, the body goes farther from one thing and go nearer to another thing.

For example, if a person went to office from home, when it moves the person goes nearer to the office and far away from the home.

Types of motion :
