Question

Which of the following is/are true for an object in circular motion?

• A. It follows a circular path.
• B. It passes through the initial point again and again.
• C. The motion of the object can be periodic.
• D. It is in rectilinear motion.

Answer 1

Answer: (A), (B), (C)

The correct options are
A

It follows a circular path.

B

It passes through the initial point again and again.

C

The motion of the object can be periodic.

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