Yes, thank you! Even if it's a simple answer, it definitely points me in the right direction, which is exactly what I was looking for. The article you posted looks great too.

Aren't we certain that d|v|/dt =/= |dv/dt|? |v(t)| = v(t) and the derivative of v(t) is a(t) Then the derivative of |v(t)| would also be a(t) a(t) is not |a(t)| Therefore, the derivative of |v(t)| is not |a(t)|. So we know they aren't the same. Correct me if I have any mistakes...

I've heard that a changing magnetic field creates an electric field and vice versa. So if shoot an electron in a straight line, it would create a magnetic field in a circle around it. Let's say the electron is moving quickly down a road. But there is another particle moving exactly the same...

Yeah, I took a look at that thread before posting, but after a couple of posts the conversation spirals off into something I don't understand too well. Looking at that previous thread, it seems that the reasons are the strong force, the electromagnetic force, and the Pauli exclusion principle...

Hello 256bits, I took a look at those pages, but as usual with Wikipedia's science pages, I quickly ran into concepts and terminology I wasn't familiar with, and clicking on them only lead to more terms and concepts I wasn't familiar with. That's why I come to a forum, I'm looking for an...

That stuff wasn't wrong, it's just that when I googled "Does the strong force repel" I only got things saying that it attracts. I know that they have finite size and repulse, but I didn't understand why. My guess would be that a neutron is a bundle of quarks, which do have electric charge, and...

Sorry I misspoke. If we take a hydrogen atom, we have a stationary proton in the center, and then its electron is moving about on the outside somehow. So the electron is moving and the proton is not. The electron would create a magnetic field and the proton would not. So there would be a net...

Hello Vanadium 50, that is very closely related to my question. An admittedly brief google search seemed to indicate that the strong force is only attractive. Perhaps I was mistaken. I'll take a look at those links, 256bits, thank you.

They are moving in orbit around a proton.

Ok, so I understand about the situation when I lift my arm, but not about a stationary pencil. In the pencil, there are effectively a bunch of protons, which are not moving, and a bunch of electrons which are moving very rapidly. Since the electrons are the only ones moving, they create a...

I think I understand now. Your question about how I would draw it really helped. Thanks! I have a bunch more questions, if you're still willing to help. When I look up why the sky is blue, I'm told the reason is blue light has a shorter wavelength, so it bounces into atoms in the sky more...

I'm confused about how a particle like a neutrino or a neutron has a cross section in the first place. When I think of two particles colliding, I think of the two particles approaching each other, and then some force repels them after they get too close. For two atoms, it is that the electrons...

I'm not sure how I would draw it because I am not certain of what I am drawing. Edit: That's not a very clear thing to say, sorry. I think I am beginning to understand now. Give me a moment to think about it.

Did you receive my personal message?

I'll try another link: https://encrypted-tbn0.gstatic.com/images?q=tbn:ANd9GcSl6rEODenuFlyiFPOf7sZGLBFvtNKaNfz2JqzKMVboSx3Iq076 In this picture there are black, blue, and yellow axes. So I'll use that terminology. I was saying that the *strength* of the field is a scalar. I'm interpreting the...
