SUMMARY

The discussion focuses on the mass of a system composed of freely moving particles, questioning whether the total mass equals the sum of the individual particles' masses. It concludes that the total mass is not simply the sum due to the presence of empty spaces between particles. The participant proposes a formula for total mass, M(s), which includes contributions from holes, moving particles, and particles at rest. Additionally, they reference the relationship between energy and mass, specifically E = k.e + p.e, indicating a connection between kinetic energy and potential energy in determining mass.

PREREQUISITES
  • Understanding of modern physics concepts, particularly mass and energy relationships.
  • Familiarity with kinetic energy (k.e) and potential energy (p.e) equations.
  • Basic knowledge of particle physics and system dynamics.
  • Comprehension of the implications of empty space in particle systems.
NEXT STEPS
  • Research the principles of mass-energy equivalence in modern physics.
  • Study the derivation and implications of the equation E = k.e + p.e.
  • Explore the concept of particle interactions and their effects on system mass.
  • Investigate the role of empty spaces in particle systems and their impact on mass calculations.
USEFUL FOR

This discussion is beneficial for physics students, researchers in particle physics, and anyone interested in the complexities of mass in freely moving particle systems.

if a system of particles is composed of n freely moving particles .is the mass of this system qual to the sum of the masses of the individual particles ?
well of course no but the idea is those particles if they are freely moving so there is empty spaces and if there an empty space that those particles didnt complete the total mass of the system so i think M(s)= M(holes) + M(particles that are moving) +M(particles that are at rest) please tell me what I am missing here thank you...

ok now what can i do hmm PLEASE HELP...
 
sorry i was talking bla bla but the answer is E=k.e+p.e ,p.e=... ,k.e=... from those u can get M=km hahahah see...
