Answer
circular
Reason — In circular motion, a body moves along a circular path such that the distance of any point on the body from a fixed reference point (the centre) remains constant.
The other options are not correct because
- In vibratory motion, the body moves to and fro about a mean position
- In rectilinear motion, the motion is along a straight line
- In curvilinear motion, the path is curved but the distance from a fixed point is not constant.
Hence, in circular motion, the distance of a point on the body remains constant from a fixed reference point.
