The simplest example is an object moving in uniform circular motion. The force and acceleration are entirely centripetal. That is to...

I would like to expalin it in the case of ellipse orbit of planets as shown in the figure below. You see that F has components that is...

They can do what they like. As long as it adds up.

##\Delta m## is generally defined as the change in ##m##. If the mass reduces, then ##\Delta m## is negative. It's a common point of...

This site focuses on mainstream science. We can't discuss personal theories.

First, we need a definition of what it means for a manifold to be spherically symmetric. There is a formal definition here, in terms of...

I have always been wondering how such a banal thing can generate endless discussions.

How does dropping the arbitrary and irrelevant cause & effect assignment make applying Newton's 3rd Law more difficult? If anything, it...

Perhaps you'll find what you are looking for here. This site focuses on established cosmology, and personal theories are not up for...

For the quantum state ##|l,m\rangle= |2,0\rangle## the z-component of angular momentum is zero and ##|L^2|=6 \hbar^2##. According to...

Well, exactly! There is no realistic configuration that satisfies the requirements. I'm suprised this example isn't shown more often...

Logically you could argue that you are correct but does your approach actually help understanding or discussion. It often makes things...

I fail to see how RQM has any bearing on this. What you've written makes no sense to me, I'm sorry to say.

Particles and anti-particles are well-established in the Standard Model. What are you trying to say?

If a negative energy appears somewhere, it is always an indication of a direction problem, or in other words a geometric problem, which...
