Question

Which of the following is true with respect to periodic motion?

• A. It needs to be an oscillatory motion
• B. It needs to pass through a particular point again and again
• C. Both A and B
• D. None of the above

Answer 1

The correct option is B

It needs to pass through a particular point again and again

The motion of the moon around the earth is periodic but it is not an oscillatory motion. Hence, option A is not correct. But if an object passes through a particular point again and again in equal intervals of time, we can say that the motion is periodic. So, only option B is correct.
