Question

Explain conservation of momentum and impulse with dervationand suitable ecamples

Answer 1

Conservation of momentum is a fundamental law of physics which states that the momentumof a system is constant if there are no external forces acting on the system. It is embodied in Newton's first law (the law of inertia).
Impulse is the change of momentum of an object when the object is acted upon by a force for an interval of time.
