Question

4 what is the law of conservation of momentum? a the total amount of momentum in an open system is conserved. b the total amount of momentum in an isolated system is conserved. c the total amount of momentum in an isolated system equals the sum of the action and reaction forces. d the total amount of momentum in an open system equals the sum of the action and reaction forces.

Explanation:

The law of conservation of momentum states that in an isolated system (a system with no external forces acting on it), the total momentum remains constant. An open - system has external interactions which can change the momentum. Action - reaction forces are related to Newton's third law and not the definition of momentum conservation.

Answer:

B. The total amount of momentum in an isolated system is conserved.
