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

A

it is at rest

B

he 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 uniform translatory motion, all parts of the ball have the same velocity in magnitude and direction, and this velocity is constant.
