A vector has both magnitude and direction. Does that mean anything that has magnitude and direction is necessarily a vector ? The rotation of a body can specified by the direction of the axis of rotation and the angle of rotation about the axis. Does the make any rotation a vector ?

Text Solution

Verified by Experts

No. Finite rotation of a body about an axis is not a vector because finite rotations do not obey the laws of vector addition.
