Simple:
Inertia is the characteristic of an object that resists change in motion.
Inertia is quantified as mass. We say a 2 kg object has twice the inertia as a 1 kg object.
More:
We say that Newton's first law is the law of inertia. Basically, Newton's first law asserts that this characteristic exists and is associated with all objects.
(A thousand years ago, people believed in magic and all sorts of things, so an assertion that there is something called inertia and it is a universal characteristic is not so trivial as it might sound now. As a side note, this law of nature was known before Newton, specifically, we know that Galileo had the correct formulation.)
One quantifies this characteristic of inertia with mass. Mass is the thing that tells us how acceleration is proportional to force. We say a 2 kg object has twice the inertia as a 1 kg object. Newton's second law says this works the same for all object and the proportionality is the same for all forces.
This is called inertia.

The greater the mass an object has, the more inertia the object has, so the object resists changes to its motion better. In other words, as mass increases, the acceleration caused by a constant force decreases.
Inertia
inertia. the more mass an object has, the greater its inertia. what do you call it when an object refuses a object in motion?
inertia
Inertia is a property of matter in which an object resists a change in motion.
It resists the motion (slows it down)
Inertia of motion is the resistance mass has to motion. It also is the resistance in change in momentum. Momentum includes two things: velocity and direction. When an object changes its velocity, the momentum of the object resists the change. Also, when an object does change its velocity, its momentum is directly changed. In general, the inertia of motion is matter's unwillingness to change velocity or momentum.
The resistance of an object to changes in its motion is known as inertia. Changes in an objects motion include changes in its speed and direction.
Friction.
All objects resist a change in motion. That is Newton's first law of motion. It requires only that the object have mass. An object that is not acted on by an external force will continue in it previous state of straight line motion. The property that all object have that resists a change in motion is called inertia. The quantitative measure of the inertia of a body is called its mass. This answer applies to movement through space. There is a similar explanation for rotational motion.
