Conservation of angular momentum

Click For Summary
SUMMARY

The conservation of angular momentum applies to non-stationary reference frames, specifically within uniformly moving inertial frames. In these frames, the laws of motion remain consistent, allowing for the conservation principle to hold true. However, in rotating frames, adjustments must be made to account for forces such as centrifugal and Coriolis forces, which disrupt the straightforward application of angular momentum conservation.

PREREQUISITES
  • Understanding of Newtonian mechanics
  • Familiarity with inertial reference frames
  • Knowledge of centrifugal and Coriolis forces
  • Basic grasp of angular momentum concepts
NEXT STEPS
  • Study the principles of Newtonian relativity
  • Explore the effects of centrifugal force in rotating systems
  • Investigate the Coriolis effect and its applications
  • Learn about angular momentum conservation in various reference frames
USEFUL FOR

Physics students, educators, and professionals interested in classical mechanics and the principles governing motion in different reference frames.

Hi, can i clarify sth?

Does conservation of angular momentum apply to non stationary reference frame or like moving axis of rotation?


Thanks!

Newtonian mechanics obeys Newtonian relativity, which means that the laws of motion are the same in all inertial frames …

that is in all frames which are uniformly moving and not rotating.

So conservation of angular momentum does apply about an axis in a moving inertial reference frame,

but not about an axis in, for example, a rotating frame (where you have to make corrections known as centrifugal force and Coriolis force ). :smile:
 
okay. thanks a lot :)
