In a spinning top, axis moves around the vertical through its point of contact with the ground sweeping out a cone. This movement of the axis of the top around the vertical is known as

A

rotation

B

translation

C

precession

D

rolling

Text Solution

Verified by Experts

The correct Answer is:
c
The axis of a spinning top moves around the vertical through its point of contact with the ground sweeping out a cone as shown in the figure. This movement of the axis of the top around the vertical is known as precession.
