A ball is travelling with uniform translatory motion. This means that .

A

it is at rest.

B

the path can be a straight line or circular and the ball travels with uniform speed .

C

all parts of the ball have the same velocity (magnitude and direction) and the velocity is constant .

D

the centre of the ball moves with constant velocity and the ball spins about its centre uniformly .

Text Solution

Verified by Experts

The correct Answer is:
C
In a uniform translatory motion all parts of the ball have the same velocity in magnitude and direaction and this velocity is constant the situation is shown in adjacent diagram where a body A is uniform translatory motion.
