Question

question 223 of 288 according to the law of conservation of momentum, which statement is true about a system that has no external forces acting on it? a. the sum of the momentums of all objects in the system is always zero. b. an increase in momentum before a collision must equal an increase in momentum after the collision. c. the total momentum of all objects in the system does not change. d. the momentum of each object in the system remains the same before and after a collision.

Explanation:

The law of conservation of momentum states that for a system with no external forces, the total momentum of all objects in the system remains constant (does not change) before and after interactions like collisions.

Answer:

C. The total momentum of all objects in the system does not change.
