Can maas be variable? if yes then how.Also mass can be negative? |

Answer» because ...a variable-mass system is a collection of matter WHOSE mass varies with time. It can be confusing to try to APPLY Newton's second law of motion directly to such a system.NEGATIVE mass is matter whose mass is of opposite sign to the mass of normal matter, e.g. −1 kg.[1][2] Such matter would violate one or more energy conditions and show some strange properties, STEMMING from the ambiguity as to whether attraction should refer to force or the oppositely oriented acceleration for negative mass.mark this answer as brainlest PLEASE.... |
