What does negative value for potential energy mean and which is more stable in potential energy for example -3000 or -4000? I read that it doesn't mean anything and the values of the energies are usually negative.

    $\begingroup$ As in nature only energy differences matter, the point of zero energy is arbitrary. You might want to read some discussions about 'gauge invariance'. I also recommend these threads: physics.stackexchange.com/q/17082 , physics.stackexchange.com/q/560722 $\endgroup$

  • $\begingroup$ A negative potential energy of two attracting particles means smaller the resulting mass of the compound system with respect to the non interactibg particle system. $\endgroup$ Jan 18, 2021 at 13:39
  • $\begingroup$ thanks for replying so particle which has higher potential energy is more stable than which has lower potential energy ? $\endgroup$ Jan 18, 2021 at 15:17
