Each time a ball collides, its momentum as well as the product of its mass and velocity must remain constant. That is, the overall momentum prior to and following the contact must be equal.
What is law of conservation of momentum?
- According to the law of conservation of momentum, when two objects meet in a closed system, their combined momentum before the collision and their combined momentum after the collision are the same.
- Momentum is the force necessary to bring an item to a complete stop in a given amount of time.
- It is calculated by multiplying the mass of an object by its velocity.
- The total momentum of any collection of many objects is equal to the sum of its component moments.
- However, momentum is odd in that it is a vector that includes both the direction and the speed of motion.
- As a result, objects moving in opposite directions can have moments that cancel one another out to produce a sum of zero.
