Why is law of conservation of momentum important?

The Law of Momentum Conservation. ... Yet, the total momentum of the two objects (object 1 plus object 2) is the same before the collision as it is after the collision. The total momentum of the system (the collection of two objects) is conserved.

1. Measurements is process of measuring or size of something

3. Ampere is measure of the amount of electric charge per unit time

4. Electric current is the rate of flow of charge.

5. Luminous intensity: is a quantity for characterizing a light source.

6. Mole: unit of measurement for amount of substance in SI system

7. Plane angle we simply say that angle in two dimensions

Where as solid angle is in three dimensions
