Question

A ball is travelling with uniform translator 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
