In which of the following cases of motions, the distance moved and the magnitude of displacement are equal?

(a) If the car is moving on straight road

(b) If the car is moving in circular path

(c) The pendulum is moving to and fro

(d) The earth is revolving around the Sun

Answers (1)

Ans. A

Sol.

The distance is total path travelled by anybody. The displacement is shortest distance between initial and final point of the motion.

Only in the case when the body moves in a straight line without turning, the distance will be equal to displacement.

In all other cases distance will be more than displacement.

Hence the correct option of this question is option A.
