Ah, this is probably what I'm looking for.
From what I understand NOW, it is not that they have zero energy(BECAUSE they have mass), but they have 0 kinetic energy.
I'm guessing that what everyone's trying to tell me is that ƩE= mc^2 and not just KE=mc^2. Makes a lot more sense now can't...
Then wouldn't with the mass energy equivalence, if E = 0, then that means either mass has to equal zero or c has to equal zero, but according to Einstein c is constant in all FoR. So that means m has to change to zero?
Absolute zero is the theoretical state in which a system reaches 0K, or NO energy present right? And if gravity affects everything with momentum and energy, would it cease to affect absolute zero systems because it includes no energy and thus no momentum?
I posted a blog post on it here...
A. He's lying, he's actually in Argentina.
B. He pulled a random country that seemed third world enough.
C. He knows somebody in Argentina
Best guesses!
First off, this isn't really a homework question, but I'd rather post it here and look like somebody trying to learn rather than being mocked at secretly in the engineering section.
So my question is, how do batteries work, SPECIFICALLY? Down to the ditty-bit details. Every source I try to pop...
Okay bear with me here because this might get disgusting. But I was watching Henry's video on how astronauts went to the bathroom in space, and basically they did it in a bag, and shot the bag outside into outerspace. And then he mentioned that the trajectory would change(but extremely small yet...
When two waves collide, they get bigger as they go 'through' each other and then they just get to regular size again and move on. That's the way I learned about waves anyway. I believe they can cause interference with each other however.
I'd also like to add that I remember in elementary how my science teacher got a plastic cup with water in it, put a postage on top of it, flipped it, and let go of the postage and it wouldn't let go(because of atm). Her explanation? The water was sticky.
There WAS time before the big bang, but it is extremely insignificant. Read on A Brief History of Time by Stephen Hawking which delves into this very concept.
Hello PF!
What are some common things you see among peers in physics that they learned wrong in school? I'm talking about misconception(can you believe some college students think that the electrons are in a planetary orbit around the nucleus of an atom?!?). I'd like to avoid looking like an...
Just to be clear, this is NOT a homework question. It's honestly a question I have pondered for as long as I can remember sitting on the backseat of my family's minivan with a rubber ball.
I'd also like to clear out that you bear with me and if I look unintelligent or questionably retarded...
