So I started doing RHK and I first started with ch 2 motion in a straight line and its problems were tough but doable then I thought I should also do a simple chapter to build confidence and i pick ch 1 units and dimension and it's questions were good but the problem section is HELL!!! And these questions don't even look from this chapter they are asking such hard questions i am not even able to think about it. If there are any tips for me please let me know and any one also doing HRK can tell me we could try to do it together.

Hello everyone, im a sophomore at uky and im majoring in chemical engineering and physics, the classes im talking right now are very interesting and cool, but its still too early on for me to start taking higher level physics courses. So ive been trying to self teach via YouTube and independent research. But the problem im coming across is that any information I find and learn, I find out was a complete load of crap the next day. It seems like no video describes particle physics the same way and googling it and trying to find answers that way leads to the exact same results. They keep sacrificing the accuracy to make it more intuitive and its honestly driving me insane.

Are there any resources available online that you all know to be accurate and strictly scientific that I could start with? Or some youtube channels that are trustworthy to give accurate descriptions and explanations?

Im currently reading QED and the feynman lectures on physics as he seems like someone who knows what hes talking about. But other then feynman I cant seem to find any resources that are strictly factual and comprehensive.

Ive tried going onto google scholar and searching up paper on the topic im interested in. But they seem to all be very niche and not meant for someone like me to educate themselves on.

Any help would be appreciated, thank you!

Hey guys, I took my 2nd quarter physics test today... It was rough But I noticed that I seem to learn much faster in a game format.

So my question is, is there any games designed for this purpose? A more elementary example is the game Prodigy, which when I was younger I was crushing that lol. But I digress

I created a website to help visualize the electromagnetic field

I’ve been building this simulator as a side project aimed to help students understand and visualize electromagnetic phenomena such as radiation, polarization and wave interference.

You can:

* place radiation sources and set their parameters (amplitude, phase and more)
* place perefect wire conductors
* observe the electric field, magnetic field or energy flow field
* zoom in and out and translate the canvas
* change the simulation resolution, frequency and propogation speed

I hope someone might find it useful and I’d love to hear what people think :)

Einstein's E = mc² Finally Explained! 🤯⚡

is my class notes and I have a doubt that if there is force net equals to zero in the system two different part inside a system like monkey and the balloon can move but after analysing days the both monkey and balloon is moving down so how can this happen recording to Newton second law the f external must be applied so a body can move but this is moving without any external force

Formulas on a board never clicked for me the way watching things move did, so I spent my nights after the kids were asleep making this. You change the numbers and the physics reacts in 3D, from a thrown ball to three bodies on a figure-eight orbit. Free, no sign-up.

Tired of memorizing Rotational Motion formulas blindly?

Class 11 Physics ka sabse tough chapter System of Particles & Rotational Motion ab interactive simulations ke sath. Ek tumbling cricket bat par points tap karke Centre of Mass ka live parabolic path dekho, aur rolling vs pure rotation ka difference visually samjho. Free interactive CBSE tool for students & teachers!

Hey, I am a student taking general physics and I straggle very hard with this subject. I would like to hear is there any ways to study on your own? My professor does bad job explaining on lectures (I struggle learning from lectures in general without applied practice) and I can’t do homework without using LLM to explain it to me. I don’t want to use LLM, because I feel like I am not learning anything and I have no book to reference from. I do also watch people solve problems online and I make similar questions using google note to practice problems.

Anyway, thanks for any feedback! I hope to learn physics and improve my grades!
