Question

What is Momentum and its Importance?

Answer 1

Explanation for Momentum

1. Momentum is the product of mass with velocity.
2. It has both magnitude and direction.
3. It is a vector quantity.
4. The formula of momentum is given as:$p=mv$,where $p$ is the momentum, $m$ is the mass, $v$ is the velocity.
5. The unit of momentum is $\mathrm{Newton}-\mathrm{second}$.
6. Momentum in physics notion relates to how much motion an item possesses.

Importance of momentum

1. Momentum is important as it describes the relation between speed, mass, and direction.
2. It also describes the force needed to stop an object in movement.
3. Due to its enormous momentum and extremely high velocity, a bullet with little mass has a lot of power.
4. When the body is in a condition of rest, momentum does not exist.
