2.The length covered by the moving body is called the distance.

3.Displacement is the shortest distance between two points.

4.distance is always greater than or equal the displacement.

5.Distance cannot have negative values.

6.distance cannot be zero.

7.Displacement is always lesser than or equal to distance.

8.displacement can have negative values.

9.when a body travels unequal distances in unequal intervals of time the object is said to undergo nonuniform motion.

10. when a body travels equal distances in equal intervals of time,the body is said to undergo uniform motion.
