Question

difference between rotatory motion and spin motion?? ​

Answer 1

Explanation:

the motion of a body about its own axis

( the line passing through centre of mass)

is called spin motion

A rotation is a circular movement of an object around a center (or point) of rotation. A three-dimensional object rotates always around an imaginary line called a rotation axis.

and earth posses both rotatory and spin motion

the difference is only that the imaginary line around which body moves is passes through centre of mass for spin

but it is perpendicular to the body centre

for rotation
