Question

state the law of conservation of momentum class 9​

Answer 1

Answer:

The principle of conservation of momentum states that if two objects collide, then the total momentum before and after the collision will be the same if there is no external force acting on the colliding objects.

Answer 2

Law of Conservation of Momentum:

The law states that :

• In absence of any external force, the total momentum of a system (containing 2 or more bodies) will always remain constant.

• For example : when a gun is fired, total momentum of the gun and the bullet will always remain constant.

Mathematically, we can say:

$\boxed{ \bf m_{1}u_{1} + m_{2}u_{2} = m_{1}v_{1} + m_{2}v_{2}}$

• Similarly, for collision between 2 object, the total momentum before and after the collision will remain constant.
