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
- Alinear momentum of the system does not change in time
- Bkinetic energy of the system does not change in time
- Cangular momentum of the system does not change in time
- Dpotential energy of the system does not change in time
