Which among the following is/are the characteristic(s) of a circular motion?
It follows a circular path
It passes through the initial point again and again
It can be periodic
In the case of circular motion, if we trace the path followed by the object, it is a circle. Now we can also observe that 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. The particle does not follow a straight line path, so it is not a rectilinear motion.
