Why is angular momentum not conserved in 2 similar mass planet system?

Click For Summary
SUMMARY

The discussion centers around the conservation of angular momentum in a system of two similar mass planets. It concludes that angular momentum is not conserved without the proper context, such as external forces or interactions that may influence the system. The participants emphasize the importance of understanding the specific conditions under which angular momentum conservation applies, particularly in gravitational interactions.

PREREQUISITES
  • Understanding of classical mechanics principles
  • Familiarity with angular momentum concepts
  • Knowledge of gravitational interactions
  • Basic physics of multi-body systems
NEXT STEPS
  • Research the conditions for angular momentum conservation in multi-body systems
  • Study the effects of external forces on angular momentum
  • Explore gravitational interactions in celestial mechanics
  • Learn about the role of torque in angular momentum changes
USEFUL FOR

Students of physics, astrophysicists, and anyone interested in understanding the dynamics of celestial bodies and the principles of angular momentum in complex systems.

The two mass is similar. I read a line about this and i thought L should be conserved before. What is the background knowledge behind? Thank you.

I read a line about this...
Where did you read this line?

There is no way to answer this question without the proper context.
