Mass and free fall speed under gravity

Click For Summary
SUMMARY

The discussion clarifies that mass does not increase with speed, countering the misconception surrounding "relativistic mass." Participants emphasize that this concept is largely obsolete and recommend consulting resources that explain the distinction between rest mass and relativistic effects. The conversation specifically addresses the implications for particles falling into black holes or neutron stars, highlighting the importance of understanding these fundamental physics concepts.

PREREQUISITES
  • Understanding of general relativity
  • Familiarity with the concept of rest mass
  • Knowledge of black holes and neutron stars
  • Basic grasp of relativistic physics
NEXT STEPS
  • Read "What is Relativistic Mass and Why It is Not Used Much?" for a deeper understanding
  • Explore the principles of general relativity and its implications on mass
  • Investigate the behavior of particles in strong gravitational fields
  • Study the differences between rest mass and relativistic mass in detail
USEFUL FOR

Students of physics, astrophysicists, and anyone interested in the effects of gravity on mass and speed, particularly in extreme environments like black holes and neutron stars.

If mass increases with speed then what is the mass and speed of a particle falling from a large distance into a black hole or onto a neutron star?
