If the momentum of a system is conserved, is the momentum of each particle in the system necessarily conserved? Explain.
Homework Answers
Momentum of system is conserved if there is no net external
force on the system.
Particle of system can exert a non zero force on each other hence
momentum of each particle in not necessarily conserved.

When is the momentum of a system conserved? (a) Momentum is a conserved quantity, so it’s always conserved (b) Only during collisions (c) Only if the net internal force on the system is zero (d) Only if the net external force on the system is zero

Question 3: (2 pts.) When can you assume that momentum is conserved and the momentum before a collision and momentum after a collision should equal the same value? Explain using concepts of net force on the system of two carts as well as the forces on each individual cart.

15.52** (a) Suppose that the total three-momentum P = Σ p of an isolated system is conserved in all inertial frames. Show that if this is true (which it is), then the fourth component P4 of the total four-momentum P = (P, P) has to be conserved as well. (b) Using the zero-component theorem of Problem 15.35, you can prove the following stronger result very quickly: If any one component of the total four-momentum P is conserved in all frames,...

Can someone explain this statement to me? "In conclusion the momentum is conserved in both systems of collision but some energy will be lost in an inelastic system."

If the total momentum of a system is a constant, then we say that the total momentum is conserved. A consequence of Newton’s laws of physics is that the total momentum of a system is conserved whenever the net external force on the system is zero. Describe all the external forces acting on this system and explain what the net external force is. Is it zero or approximately zero?

It is been proved that Newton's third law implies the conservation of momentum for a system of particles if there is no net external force. For a System of interacting particles, prove the converse: if total momentum for the two particles is conserved in absence of a net external force, then the inter particle forces must obey third law of Newton.
