Question

Which of the following is/are the characteristic(s) of an object in circular motion?

• A. It follows a circular path
• B. It passes through the initial point again and again
• C. It can be periodic
• D. All of these

Answer 1

The correct option is D

All of these

Suppose we take a particle undergoing circular motion. If we trace the path followed by the object, it is a circle. Now we can also observe it passes the initial point again and again. If the particle moves with constant speed, then it passes the initial point after equal intervals of time, so it can also be periodic. But the speed of the particle might change during the motion; in that case, it will not pass through the initial point after equal intervals of time. So circular motion can be periodic but it is not necessary.
