PeroK replied to the thread High School Straightforward integration….I'm not sure why you are calculating an indefinite integral. The first rule of mathematical physics is that the first term in a parts... -
PeroK replied to the thread High School Straightforward integration….I'm struggling to see what you are doing with integration by parts. I applied parts twice, with the initial tern vanishing at both end...

PeroK replied to the thread High School Individual photons or electrons on a screen?.I'm not an experimentalist. Hopefully, someone else on here can give you a satisfactory answer. In the meantime, you could do your own...

I got my degrees in general physics and geophysics and it’s been a long time since then and I am having a hell of a time finding people...

PeroK replied to the thread Undergrad Light clock treating horizontal and vertical motion differently?.Let's take that as your argument that physics generally is no good. So, what do we do? Get out the new-age crystals? Rely on ancient...

PeroK reacted to vela's post in the thread How do I derive an expression for the velocity vector for any α? with Like.
You have $$a = v \frac{dv}{dx}$$ where ##x## is the displacement. As the block initially moves to the right, you have ##x=s##, so the...

it is not simple harmonic motion

PeroK replied to the thread How do I derive an expression for the velocity vector for any α?.The question is a bit odd. Presumably, the bar does not get lifted off the surface, so that we have an assumed constraint of motion in...

A common misunderstanding, but it was never trained to be correct or consistent. It was trained to be similarly satisfying as its...

PeroK replied to the thread No freewill?.Define "exists". Show me the future if it "exists". Tell me what happens tomorrow if it "already exists". You are just playing with...

PeroK replied to the thread No freewill?.There's nothing inherent in the theory of relativity that pertains to freewill. Freewill could be described as a measure of our ability...

PeroK replied to the thread Difficulty understanding the reasoning behind constraint equations in mechanical systems.Actually, I'll ask that this thread is moved to homework. Just post your working on this thread.
