The law of conservation of momentum states that

Question

a
the total initial momentum of all objects interacting with one another does not equal the total final momentum.
b
the total initial momentum of all objects interacting with one another usually equals the total final momentum.
c
the total momentum of all objects interacting with one another is zero.
d
the total momentum of all objects interacting with one another remains constant regardless of the nature of the forces between the objects.

Answer 1

The correct statement regarding the law of conservation of momentum is:

d the total momentum of all objects interacting with one another remains constant regardless of the nature of the forces between the objects.

This means that in an isolated system (where no external forces are acting), the sum of the momenta of the objects before an interaction (like a collision) is equal to the sum of their momenta after the interaction.
