Conservation of angular momentum axis

Click For Summary
SUMMARY

Angular momentum conservation applies to systems where no external torque acts on them. In the context of a rod struck by a ball, angular momentum can be conserved about the center of mass or any point along the base of the rod. However, if external forces or torques are introduced, such as friction or an external push, conservation principles may not hold. Understanding the specific conditions under which angular momentum conservation is valid is crucial for solving related physics problems.

PREREQUISITES
  • Understanding of angular momentum and its conservation principles
  • Familiarity with torque and its effects on rotational motion
  • Knowledge of center of mass calculations
  • Basic physics concepts related to forces and motion
NEXT STEPS
  • Study the principles of torque and its impact on angular momentum

  • Explore examples of angular momentum conservation in various physical systems
  • Investigate the effects of external forces on angular momentum conservation
USEFUL FOR

Students studying physics, particularly those focusing on mechanics and rotational dynamics, as well as educators looking for clear explanations of angular momentum concepts.

Homework Statement



about
what point and about what kind of axis can we conserve angular momentum?can we conserve it about a point moving in circular motion?

Homework Equations





The Attempt at a Solution


its just a understanding based question to apply to problems
 
Physics news on Phys.org
Conservation of angular momentum is a phenomenon and not a quantity which may have point, direction etc.
I don't understand your next question. But I think this may help you-You don't need to conserve the momentum, rather it's in nature that the momentum will always be conserved provided the fact that no external torque is given.
 
i wanted to say for example there is rod standing with base on ground.u hit it say with some ball or anything it will begin to rotate.on ball+rod system about what point (centre of mass or point on base on ground or any other point) can i conserve angular momentum and apply equations.in which case i would be wrong to conserve it and why?
