Question

How are inertia and mass related?

Answer 1

Hint: Mass is the amount of matter in an object. Inertia is the property of an object or the tendency of an object to resist the change in its motion. The objects with more mass weigh more than the objects with less mass. A heavy object will have more inertia than a lighter object.

Complete step-by-step answer:
Mass is the amount of matter in an object. The objects with more mass weigh more than the objects with less mass. A heavy object will have more inertia than a lighter object.
Inertia is the tendency of an object to resist the change in the motion. OR The property of an object because of which it resists to get changed its state is called the inertia.
Newton’s first law of motion states that an object at rest or in motion will remain in that state, until and unless compelled by an external force. Thus, inertia is a natural tendency of objects to resist the change in their state of motion.
Inertia increases as the mass of an object increases. Inertia is directly proportional to the mass, that is, inertia increases with the increase in the mass and decreases with the decrease in the mass.
The SI unit of the mass is kg and the SI unit of the inertia is also kg.
$$\therefore$$ The mass and the inertia are directly proportional to each other

Note: Newton explained that an object’s mass is a measure of its inertia. In other words, the objects with different masses moving at the same speed, the one with the greater mass has the greatest inertia. Inertia solely depends on the mass of an object.
