Best ResponseYou've already chosen the best response.2is conserved ,when no force act on system that you define .maybe you define a system that force act on it so total momentum is not conserved for more information see Wikipedia

Best ResponseYou've already chosen the best response.2suppose this figure :dw:1329061665329:dw momentum will not conserve ,if you take body(just body) for system ,hence friction act on system,now assume body+ground for system here momentum will conserve hence all of force that act ,are interior

Best ResponseYou've already chosen the best response.0so if i understand u it means it in a change of momentum the forces acting are in the system then momentum is conserved and if the forces acting are not part of the system then momentum is not conserved e.g friction

Best ResponseYou've already chosen the best response.2if you see this you can find a good risult for conservation of momentum http://hyperphysics.phyastr.gsu.edu/hbase/conser.html#conmom
