Question

Find the odd one out and give reason:


(i) Translatory motion, rectilinear motion, curvilinear motion, rotatory motion.

(ii) Falling stone, a car running on a straight road, revolving fan, an aeroplane heading towards east.

(iii) Weight, speed , velocity, acceleration.

Answer 1

Explanation:

1. Rectilinear motion and translatory motion is in straight path but rotatory motion has circular path
2. Falling stone ,car running , aeroplane moving towards east all are moving but revolving fan is rotating at fix position
3. weight donot depand on distance travel per unit time but remaning three depand on distance or displacement travel per unit time

Answer 2

1) rotatory motion ( because all other motions are followed as a straight path)

2) revolving fan ( because the other actions follow straight path )

3)weight ( because the other three are related to motion )
