In summary, this discussion is about the mathematical and physical uses of the symbol "m0". Various operations can be performed on it, but in physics, for a certain particle, m0 is an invariable. Without knowing more about the context, it is difficult to provide help.

The symbol "m0" means stationary mass, but what does "m0 → 0" mean in physics?

As with just about all such questions, it depends on the context... so you'll have to tell us where you came across this expression before we can help you with it.

@ Nugatory:
I encountered such a question in another site last month. But now piggy is here and reluctant to link those context. Ah, can we go on with the topic in a way as below?

In math we can consider that “m0” is just a mathematical symbol. We can carry out such mathematical operations as “m0 → ∞ ” or “m0 → 0”.
But in physics, for a certain particle, (if no other miscellaneous factors meddle in), m0 is an invariable.

If you refuse to tell us what this is all about, how do you expect us to help you?

It is true that ##m_0## is often used to represent the rest mass of something, especially in the context of special relativity, but that's not the only way it’s used. And even in that specific context, the notation ##m_0\rightarrow 0## might be part of a discussion of how a particular physical system behaves if we replace one part of with something less massive... or it might be something completely different.

So there is no answer to your question unless and until you supply that context.

You can be sad about my post all you want. But it is nevertheless true that if you refuse to tell us what this is all about, we can't help you.

Your "case" has neither an m0, nor a zero, nor a discernible point.

With that being the case, the thread is now closed.
 

What does "m0 → 0" mean in physics?

"m0 → 0" is a mathematical notation used in physics to represent the limit of a variable, in this case m0, approaching zero. It indicates that the value of m0 is getting closer and closer to zero, but is not actually equal to zero.

Why is "m0 → 0" important in physics?

In physics, "m0 → 0" is often used to represent the concept of an object having negligible mass. This is important in many equations and theories, such as the theory of relativity, where the mass of an object can greatly impact its behavior and interactions with other objects.

How is "m0 → 0" related to the concept of inertia?

Inertia is the tendency of an object to resist changes in its state of motion. When "m0 → 0", the object has very little mass and therefore very little inertia. This means that it will be easier to change its state of motion, such as accelerating or decelerating.

Can "m0 → 0" ever equal zero?

No, "m0 → 0" is a mathematical notation and not an actual value. It represents the limit of a variable approaching zero, but not actually reaching it. In physics, objects with zero mass are considered massless, and there are very few, if any, known objects with exactly zero mass.

How does "m0 → 0" differ from "m0 = 0"?

"m0 → 0" and "m0 = 0" have different meanings in physics. "m0 → 0" represents a limit, while "m0 = 0" represents an equality. In other words, "m0 → 0" indicates that the value of m0 is approaching zero, but not necessarily equal to it, while "m0 = 0" means that the value of m0 is exactly zero.
