Angular momentum is a conserved quantity, meaning its total value remains constant within a given reference frame over time. The discussion clarifies the distinction between "conserved" and "invariant," emphasizing that while angular momentum is conserved, it is not invariant across different reference frames. The relationship between apparent spin rate and mass increase at relative velocities is explored, confirming that these factors do not alter the conservation of angular momentum.

kmarinas86 said:Angular momentum must be conserved. Does that mean that if a particle travels at relative velocity to an observer that the decrease in apparent spin rate will be offset by the increase in mass causing the angular momentum to be constant?
