Explain conservation of linear momentum by suitable example.

1.	Explain conservation of linear momentum by suitable example.
Answer» SOLUTION :Lawofconservationof linearmomentumcan be obtainedby usingnewtonsecondlaw andthirdlaw ofmotionwhenbulletis firedfromgunbulletmovesinforwarddirectionand gunmoves L in backwarddirection. Initiallyboth areat resthencechangeinmomentum of bothequalto finalmoementum . Letfinalmomentumof gun be `VEC( p)_(g)`and bullet be`vec(p)_(b )` then thustotallinearmomentumof sytemis conserved. Thusforisolatedsystemtotalfinalmomentumis l equalto totalinitialmomentum LAWOF conservationof linearmomentumisuniversaland fundamental . itequallyholdtrueof systemof smallerparticleslikeelectronprotonneutron as well as largersystemmadeup of electronprotonneutron.
