Question

what do you understand by inertia? state law of conversation of momentum​

Answer 1

Answer:

Inertia is defined as the resistance offered by a body to oppose the change in its natural state .

law of conservation of momentum states that the total initial momentum is equal to the total final momentum .

hope it helped and please mark as brainliest:)

Answer 2

Law Of Inertia

It is that tendency of an object to maintain its state of motion i.e,rest or uniform rectilinear motion and it's direction. An external force is required to do so.It relates to Newton's Second Law of Motion.

Types of Inertia are:

• Inertia of Motion
• Inertia of Rest
• Inertia of Direction

Law of Conservation of Momentum

The sum total of momentum before collision and after collision of particles remain conserved or in a state of equilibrium unless the system of particles is acted upon by an external force

Mathematically,it is represented as m1u1 + m2u2 = m1v1 + m2v2
