Question

what is the measure of an object's inertia?

Answer 1

• Mass is the measure of an object's inertia.

       If the mass is more the inertia will also be more.

For, example if we consider a truck and a ball, among the two truck has a greater mass and therefore will have a greater inertia as compared to a ball.

• Newton's first law of motion is the law of inertia.

• The tendency of a body to resist change is called inertia.

• It states that a body that is in motion will continue to do so until and unless any external force is applied to it

• Similarly, a body that is at rest will remain at rest, if no external force is applied to it.

Answer 2

The inertia of an item is measured by its mass.

If the mass is more, the inertia will be greater as well.

Consider a truck and a ball. The truck has a higher mass and, as a result, has a higher inertia than the ball.

The law of inertia is Newton's first law of motion.

Inertia is the tendency of a body to resist change.

It says that a moving body will continue to move until and unless it is acted upon by an external force.

Similarly, if no external force is applied to a body at rest, it will stay at rest.
