Question

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

Answer 1

Answer: (C)

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

Answer 2

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