What is happening on an atomic level (or lower) when a object is in motion (inertia)?

If you have an iron ball and throw it upwards you are imparting a force which opposes gravity. Initially this force is easily understood by your hand pushing the ball upwards, so the atoms in your ...

How does classical, Newtonian inertia emerge from quantum mechanics?

From my understanding, inertia is typically taken as an axiom rather than something that can be explained by some deeper phenomenon. However, it's also my understanding that quantum mechanics must ...

Photon follows law of inertia? [closed]

Is the law of inertia compatible with quantum mechanics? If yes, how? And if a particle is both present and absent at the same time, (the uncertainty principle: stating that when an electron is on ...

Do photons have inertia?

We all know the example where we say that a massless box containing photons has inertia, because the photons exert pressure of the inner walls of the box. But my question is about a single photon ...

Changing effective mass of electron using electric potential?

The Dirac equation for an electron in the presence of an electromagnetic 4-potential $A_\mu$, where $\hbar=c=1$, is given by $$\gamma^\mu\big(i\partial_\mu-eA_\mu\big)\psi-m_e\psi=0.\tag{1}$$ I assume ...

Why is Quantized Inertia considered pseude-science? [closed]

In the criticism section of the Wikipedia article to Quantized Intertia it is stated that QI is considered pseudo-science. Unfortunately none of the linked but in none of the provided links can I find ...

Does "Quantized Inertia Theory" violate conservation of momentum? [closed]

This recent news article reports that DARPA is doing work with "quantized inertia", despite their claim that it's not widely accepted by physicists: The Defense Advanced Research Projects Agency (...

Does modern physics have any explanation for what causes inertia? [duplicate]

I remember Richard Feynman stating on a few occasions (like here, in lecture 1, around 21:10) that physics has no explanation of what causes inertia, that it seems to be some sort of deeply mysterious ...

Inertia of a box of photons

Suppose a box one light year long (along its x-axis) with some mass M also contained a bunch of high energy photons with energy E that were travelling along the x-axis. Would the inertia of the box ...

Influences on wavefunction path analysis

I was looking at simulations of a wave going through a slit. When the wavelength was much smaller than the slit width, the wave went through the slit and kept going straight like a laser beam. But ...

Does a wave have inertia?

In de Broglie hypothesis, particles have wave nature. The question is does this wave have inertia? If so is it represented in the corresponding wave equation?

Clarification on inertial mass

I was talking to my friend the other day about the origin of inertia and it pondered both of our brains. I would like to know if the concept of inertia exists at the quantum level? I realize that ...

How does electron spin change instantaneously without violating inertia principle?

The inertia in one of the main properties of matter. That is why all process in macro world do not happen instantaneously. What I do not understand is how we should apply this general idea of inertia ...
