Why does a high mass object under weightless conditions exhibit inertia?

That's because inertia does not depend on weight.
An object's mass causes two effects:
One is the gravitational interaction (force) with other masses. This is proportional to both masses (also, the force decreases with distance).
The other is inertia - if an object has mass, then it requires an effort to change its velocity.
Inertia depends on the mass - NOT on the weight. Weight also depends on the mass. However, weight also depends on the mass of other objects - for example, on Earth, our weight depends on the gravitational field of planet Earth.

Why is an object considered weightless when there is no normal force or when an object is in freefall?
Any object is weightless.
How can the inertia of an object be determined?
As it turns out, inertial mass is equivalent to gravitational mass, so if you simply weigh an object, you can determine both its weight and its inertia. These are always in direct proportion; twice as much weight equals twice as much inertia. The main difference is that weight does change in different locations; an object can become weightless while in orbit, while inertia does not change. But here on the surface of the Earth, it is very simple to weigh an object and get a meaningful result which applies both to gravitational mass and inertial mass. If you were in orbit, then the problem becomes a bit trickier.
What is measure of inertia of an object?
inertia is a plant
Does an object have to move in order to have inertia?
No. An object that has a lot of mass and is hard to move has inertia.
How would zero gravity affect inertia?
Zero gravity does not affect inertia. The inertia of an object is an inherent property of the object and is directly proportional to the object's mass.

How come an object can never be weightless?
gravity and mass...

No. An object that has a lot of mass and is hard to move has inertia.
How is inertia related to matter?
matter is not related to inertia. Mass is.
Is the weight of an object determined by the pull of inertia?
No. The weight by an object is related to the object's mass. Inertia is a separate effect, also due to mass - but there is no such thing as a "pull of inertia".
What gives an object inertia for newtons laws?
Nothing gives an object inertia. Inertia is not a force. It is just the tendency of an object to continue in its motion if there is no force acting upon it.
How would zero gravity affect inertia?
Zero gravity does not affect inertia. The inertia of an object is an inherent property of the object and is directly proportional to the object's mass.
What is it when an object resists any change in motion?
inertia. the more mass an object has, the greater its inertia. what do you call it when an object refuses a object in motion?
Why isn't and object free fall really weightless?

What are the conditions for an object to stay at restto keep moving at constant velocityor to move with increasing velocity?
You have three separate situations here:1. Object stays at rest. The force on the object is not great enough to overcome its frictional forces, or its inertia.2. Object keeps moving at constant velocity. The object's inertia and frictional forces are exactly balancedby the Force exerted on it.3. Object moves with increasing velocity (acceleration). The Force on the object exceeds that necessary to overcome its inertia and its frictional forces.
