Detailed explanation-1: -So if the velocity is doubled, the momentum is doubled; the new value would be two times the original value. And if the velocity is tripled, then the momentum is tripled; the new value would be three times the original value.
Detailed explanation-2: -Momentum is of interest during collisions between objects. When two objects collide the total momentum before the collision is equal to the total momentum after the collision (in the absence of external forces). This is the law of conservation of momentum. It is true for all collisions.
Detailed explanation-3: -Answer and Explanation: If the momentum of an object is tripled than its kinetic energy will increase by a factor of nine. To understand how this works, we first need to identify that velocity is directly proportional to momentum based on its equation. As momentum increases, velocity also increases.
Detailed explanation-4: -The law states that when two objects collide in a closed system, the total momentum of the two objects before the collision is the same as the total momentum of the two objects after the collision. The momentum of each object may change, but the total momentum must remain the same.
