- Its magnitude is greater than the distance travelled by the object.
A boy walks from his classroom to the bookshop along a straight corridor towards North. He covers a distance of 20 m in 25 seconds to reach the bookshop. After buying a book, he travels the same distance in the same time to reach back in the classroom. Find (a) average speed, and (b) average velocity, of the boy.
Is displacement a scalar quantity?
Differentiate between distance and displacement.

Assertion: Displacement of a body may be zero when distance travelled by it is not zero.
Reason: The displacement is the shortest distance between initial and final position.
Displacement magnitude can be greater than the distance traveled by the object.
