yes, the physics of inertia apply everywhere that inertia will be
Inertia will not be affected when "net" or "net force" is zero.
it is not
Inertia will not be affected when "net" or "net force" is zero.
No, the two are entirely different concepts.
It describes motion when net force is zero.

Inertia is not really a tool to be used... Inertia is basically an object's resistance to being moved. It stems from Newton's 2nd law of motion, which states that the net force on an object is equal to it's mass multiplied by its acceleration. Fnet=ma. So, the larger the mass of the object, the more force is required to accelerate it. To actually answer the question completely, we have to consider every situation in which an object has a net force on it, and so you really can't do that because it happens every day, every where, on virtually everything. Consequently, I'll provide a couple of examples instead... Inertia is used for ice skating... Inertia is the reason that an ice skater can glide long distances across the ice without pushing off. This is because the friction force of the ice (which is trying to stop her) is not high enough to make her mass decelerate. Inertia is used to annoy shoppers pushing shopping carts... When you push the shopping cart, you apply a force to it. The heavier the cart, the harder it is to get moving. Inertia describes the reason a heavier cart is harder to move.
The law of inertia (or newton's first law) states that a body remains stationary or moves with constant velocity if the net force that acts on it is zero.

Inertia resists acceleration. Inertia resists a change in the state of motion of a particle or rigid body. For instance, in order for the state of motion of an object to change, there must be a net external force exerting on the object, which is defined as mass times acceleration. Resistance to this net external force would therefore have to resist the object's acceleration, and that is inertia.
Unless acted on by an unbalanced force, an object will maintain a constant velocity
This would be known as the net-force.
