why does mass have inertia?

Question

never mind these conditions are impossible. assume a object in a void. no other mass exist. will the object have inertia? please don’t consider what’s going on inside the object. I would like to know if it has inertia or not and why?

Answer 1

Inertia is whether the object moves. If it does not move its inertia is zero (no movement)
If a force is applied it will have an inertia relative to the amount of force x mass

Answer 2

Yes it would have inertia. Inertia is defined as The tendency of an object at rest to remain at rest, and of an object in motion to remain in motion. If left alone in the void the object would remain still. If your were to push it. It would never stop moving until it came in contact with some resistace. ie friction from atmosphere.

Answer 3

Asking why for anything is an unanswerable question. Why is heat hot? Why is sharp not dull. Why is English a language?

So I can't say why.

But yes, any mass has inertia. It depends only on the mass and not on other masses in the universe and not on anything going on inside. Mass just has inertia. It is an observed fact.

Answer 4

Mass possesses the characteristic of intertia, even if it's the only mass in existence. Why mass has inertia is not known, but most physicists believe that it's due to something called the Higgs boson, a particle that so far has not been detected.

Answer 5

Mass is the measure of inertia.
Inertia is the tendency of a body to resist change in its state of motion.
Eg.
A body of mass 20kg will have more inertia than a body of mass 10kg.

Answer 6

Think about newton's law that states that an object in motion stays in motion unless acted upon by an outside force,

Answer 7

Like, a universe with only 1 electron, and nothing else? Under such conditions, it would be a mystery if time and space would exist, or even what "existence" means.
