Question

The law of conservation of angular momentum is a consequence of

a) Homogenity of time
b) Homogenity of space
c) Isotropy of space
d) None of these ​

Answer 1

Explanation:

The law of conservation of angular momentum is a consequence of

d) None of these

Just as linear momentum is conserved when there is no net external forces, angular momentum is constant or conserved when the net torque is zero. We can see this by considering Newton's 2nd law for rotational motion: ... This is an expression for the law of conservation of angular momentum.

Answer 2

It is the consequence of the Isotropy of Space

• The isotropy of space is the requirement that physical laws continue to hold true when rotated via a stable angle. In other words, space is the same in all directions.
• As a result, spatial isotropy leads to the angular momentum conservation.
• The fact that spinning systems' spin does not change unless they experience an external torque is a basic property of such dynamic systems.
• An example of the phenomenon is an ice skater whirling.
• Due to the little friction between the skates and the ice, the torque, or spinning effect of the force, is virtually equivalent to zero. Very little distance separates the friction from the pivot point.
