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.

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.
The property of matter that resists changes in motion is inertia. Inertia is the tendency of an object to maintain its current state of motion, whether it is at rest or moving at a constant velocity.

An object resists changes in its motion due to its inertia, which is its tendency to maintain its current state of motion. This property is a result of the object's mass and is described by Newton's first law of motion. Inertia causes an object to resist changes in its velocity, whether that be maintaining a constant velocity or resisting acceleration.
The property of matter that resists changes in motion is called inertia. It is a fundamental principle in physics stated by Newton's First Law of Motion that an object at rest tends to stay at rest, and an object in motion tends to stay in motion unless acted upon by an external force.
The quantity that characterizes the inertia of linear motion of a body is mass. Mass is a measure of the amount of matter in an object and is a fundamental property that resists changes in the object's motion.
The property of a body that resists a change in movement is called inertia. Inertia is a measure of an object's resistance to changes in its velocity. An object will remain at rest or in uniform motion unless acted upon by an external force, as described by Newton's First Law of Motion.
The property of matter that resists change in motion is inertia. This means that an object at rest stays at rest, and an object in motion stays in motion unless acted upon by an external force, in accordance with Newton's First Law of Motion.
The tendency for matter to resist change in motion is called inertia. Inertia is Newton's first law of motion.
An object with more mass will have greater inertia, meaning it will be harder to change its state of motion. This is because the mass of an object is directly proportional to its inertia. Inertia is a property of matter that resists changes in motion.
Inertia is the property of any object that resists any change in its state of motion. It is described by Newton's First Law of Motion, which states that an object at rest will stay at rest, and an object in motion will stay in motion unless acted upon by an external force.
There are three types of inertia: inertia of rest (object at rest tends to stay at rest), inertia of motion (object in motion tends to stay in motion), and inertia of direction (object resists changes in its direction of motion).
If the mass is larger, the inertia is larger as well. Inertia is the property of an object that resists changes in its state of motion, and it is directly proportional to mass. Therefore, an increase in mass results in an increase in inertia, making it more difficult to change the object's motion.
