Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
According to the law of conservation of momentum, when two objects collide in the absence of outside forces ____
A
velocity decreases
B
velocity increases
C
the objects have the same momentum before and after they collide
D
the objects have more momentum after they collide than they did before
Explanation: 

Detailed explanation-1: -According to the law of conservation of momentum, when two objects collide in the absence of outside forces, the objects have the same momentum before and after they collide. centripetal force.

Detailed explanation-2: -The principle of conservation of momentum states that if two objects collide, then the total momentum before and after the collision will be the same if there is no external force acting on the colliding objects.

Detailed explanation-3: -The law of momentum conservation can be stated as follows. For a collision occurring between object 1 and object 2 in an isolated system, the total momentum of the two objects before the collision is equal to the total momentum of the two objects after the collision.

Detailed explanation-4: -For a system of interacting particles, the sum of all the interaction forces internal to the system is zero. The net force on the system is the time rate of change of the momentum of the system. For the total momentum P: If objects collide in the absence of external forces, momentum is conserved for the system.

Detailed explanation-5: -Law of conservation of momentum states that. For two or more bodies in an isolated system acting upon each other, their total momentum remains constant unless an external force is applied. Therefore, momentum can neither be created nor destroyed.
