Question

state the law conservation of linear momentum? give an example with numerical expression.​

Answer 1

In conservation law. Conservation of linear momentum expresses the fact that a body or system of bodies in motion retains its total momentum, the product of mass and vector velocity, unless an external force is applied to it.

Answer 2

According to conservation law states that a particular measurable property of an isolated physical system does not change as the system evolves over time.It states that the amount of the conserved quantity at a point or within a volume can only change by the amount of the quantity which flows in or out of the volume.
