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

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