Conservation of momentum states A) is not observed in the universe to be violate

Question

Conservation of momentum states A) is not observed in the universe to be violated given that all objects can be observed B) is all of these descriptions (except the "none" answer) C) that the total momentum is never conserved D) is like the principal for conservation of energy E) when an object decreases in momentum, then some other object in the same system will increase in momentum Conservation of momentum states A) is not observed in the universe to be violated given that all objects can be observed B) is all of these descriptions (except the "none" answer) C) that the total momentum is never conserved D) is like the principal for conservation of energy E) when an object decreases in momentum, then some other object in the same system will increase in momentum A) is not observed in the universe to be violated given that all objects can be observed B) is all of these descriptions (except the "none" answer) C) that the total momentum is never conserved D) is like the principal for conservation of energy E) when an object decreases in momentum, then some other object in the same system will increase in momentum

Explanation / Answer

Option E is correct.

From law of conservation of momentum total momentum of the system is constant when there is no external force acts on the system.

When force is rate of change of momentum F= dP/dt

If F=0, P= Constant.

On decreasing momentum of one body the momentum of other body increases, so that total momentum remains constant.
