Why we can take for granted that energy binding is associated with inertial mass?
It is common to state that a proton is bounded state of three quarks, and that the QCD energy binding (associated to a "cloud" of gluons joining together the three quarks) is responsible for ...

Equivalence of Inertia and Gravity [duplicate]
I'm now wondering...does - energy=mass=inertia=gravity? Are they all, intrinsically, the same, "thing"; that is, the same, "entity".

What is the definition of mass?
From what I have seen so far, there seem to be two fundamental criteria for considering something to have mass:
First is that it must have inertia and therefore momentum,
Second is that it interacts ...

Is inertia and gravity determined by relativistic mass or invariant mass?
As far as I know, mass fundamentally determines inertia and the gravitational force. But since there are two types of mass, which mass determines which? From what I have read so far, and correct me if ...

Inertial mass and gravitational mass [closed]
I would like to ask about gravitational mass. I know inertial mass is changing by motion (speed) according to $m=\frac{m_o}{(1-v^2/c^2)^{1/2}}$ And also that is inertial mass which sits in $E=mc^2$. ...

How can energy have inertia?
How can energy have inertia?
To my intuition, inertia is so closely associated with mass that my intuition says "Huh?"
Indirectly by mass energy equivalence it works fine, for example:
I have a ...

Mass as worldline tension?
In Special Relativity, the equation of motion of a particle of proper mass $m$ is
\begin{equation}\tag{1}
\frac{d p^a}{d \tau} = \mathfrak{F}^a,
\end{equation}
where $p^a = m \, u^a$ is the 4-momentum,...

What is meant in mass' definition 'resistance to acceleration'? [closed]
Wikipedia:
Mass is both a property of a physical body and a measure of its
resistance to acceleration
What does this mean? I know of the $E=mc^2$ formula. I think, the energy required to '...

How does inertia work at the particle level?
I've read recently that the mass of a proton is mostly not given by the Higgs mechanism. But rather it's given by the energy of quarks moving around inside the proton and gluons and other internal ...

Do the inertial mass and gravitational mass of an object depend on the frame of reference?
My understanding is that the "relativistic mass" of an object means any of the following three quantities (which are all identical):
The "mass-energy", as defined by the formula $m = E / c^2$.
The ...

Does potential energy increase inertial mass of system?
For example, we have a ball with mass m lying on the Earth. Then we lift it to a height h. So, now system Earth-ball have potential energy $E_p = mgh$. From Mass–energy equivalence system got $mass = \...

The relation between mass, inertia and energy
I have trouble understanding the following concept:
I learnt that mass is a measure of inertia, and that seemed logical enough. Yet separately I learnt that mass is a form of condensed energy. If ...

Can the origin of mass or inertia depend only of the gravitational field of matter? [closed]
The gravitacional field is directly proportional to mass or inertia. It doesn't have another property or field like this, with this power.
I think that when we apply a force to an object, the ...

Is the inertia of light equal to the inertia of mass under $E=mc^2$?
Under $E=mc^2$, 1kg of matter has $9\times 10^{10}$ joules of energy. So, if I had just the light shining from $9\times 10^8 $ 100 Watt light bulbs inside a perfectly reflective box, would that light ...

Does a box containing photons have more inertia than an empty box?
A box containing photons gravitates more strongly than an empty box, and thus the equivalence principle dictates that a box containing photons has more inertia than an empty box. The inescapable ...

An apparent contradiction to $m = m_0/\sqrt{1-v^2/c^2}$ [duplicate]
Using theoretical framework of the special relativity, we can show that the quantity that we classically regard as energy does have a property of inertia. And particularly, if the total energy of a ...
