Question

A and B are two objects with mass 6 kg and 34 kg respectively. Then which of the statements holds true?
(A) A has more inertia than B
(B) B has more inertia than A
(C) A and B both have the same inertia
(D) none of the above is true

Answer 1

Inertia is defined as the inherent property of the body which opposes any change in its state of rest or motion.
Inertia wants if a body is at rest, it should remain at rest. If a body is in motion it should remain in motion. Inertia and mass have some relationship.

Complete step by step answer:
Inertia has a direct relationship with the mass and more is the mass of the body, greater is the inertia. Since 34 kg is greater than 6 kg, therefore the body B has more inertia than B

So, the correct answer is (B)

Additional Information: Inertia is the natural tendency of a body. Mass is the quantity that is solely dependent upon the inertia of an object. In the case of rotation, we have a quantity called the moment of inertia. The role that is played by mass in linear motion, the same role is played by a moment of inertia in rotation.

Note: In the context of Newton's Second Law, mass is a measure of the inertia of an object. Greater be the mass greater is its inertia or we can say greater is the inertia greater is the mass.
