Concept Check;

The momentum of an object doesn't change unless its mass, velocity, or both change. Momentum however, can be transferred from one object to another. According to the law of conservation of momentum, if objects exert forces only on each other their total momentum is conserved.

C. Abstraction:

1. How is momentum related to impulse?

2. Why is it that the total momentum before and after collision is equal?​

Sagot :

Explanation:

1.The impulse experienced by the object equals the change in momentum of the object. In equation form, F • t = m • Δ v. In a collision, objects experience an impulse; the impulse causes and is equal to the change in momentum. ... In a collision, the impulse experienced by an object is always equal to the momentum change.

2. Law of conservation of momentum: The law states, in absence of external forces the momentum of the system is conserved. It means that the total momentum before the collision is equal to the total momentum after the collision.
