Question

Why is momentum so important?

Answer 1

Momentum:

1. Momentum is the product of the mass and velocity of an object.
2. It is a vector quantity that has magnitude and direction.
3. If $m$ is the mass of the object and $v$ is the velocity of the object then the momentum$\left(P\right)$ of the object is: $P=mv$.

Explanation:

1. Momentum gives the relationship between mass, velocity, and direction of an object.
2. Any change in momentum results in force. So, a change in momentum is used to determine the force acting upon the object.
3. The Law of conservation of momentum is formed, which states that the momentum of a system is the same before and after any event. It has wide applications in the field of physics.

These are the reasons why momentum is so important.
