If the resultant of all the external forces acting on a system of particles is zero, then from an inertial frame, one can surely say that (A) linear momentum of the system does not change in time (B) kinetic energy of the system does not change in time (C) angular momentum of the system does not change in time (D) potential energy of the system does not change in time

On a system of particles if, Sigma F text ext. =0 then, p text system = text constant No other conclusions can be drawn.

Q. If the resultant of all the external forces acting on a system of particles is zero, then from an inertial frame, one can surely say that

linear momentum of the system does not change in time

kinetic energy of the system does not change in time

angular momentum of the system does not change in time

potential energy of the system does not change in time

On a system of particles if, $Σ F_{ext.} = 0$
then, $p_{system} = constant$
No other conclusions can be drawn.
