STARTING IPHO. Hi guys, I am going to grade 10 this year and wanted to start physics olympiad preparation from basics. I dont know calc 1 too. Can you suggest me a good calculus book to get my hands on? Moreover, is it late to start my preparation? Thanks in advance.

My interest is on part (a), the steps are clear. I thought the final solution ought to be ##T- 500 =50 ×0.2## ##T=500+10 = 510N## Unless I am missing something here, same query on part (b).

My attempt: my answer was b correct answer is d

Amateur physics enthusiast. I watch a lot of physics explanation videos and one made me think of something. which would later become a paradox that i can't find any other examples of. So if that's the case I feel cool if I came up with one no one has considered before. That being said I know...

User New here but this conundrum is something that occurred to me as I was watching a physics video and I have run out of ways to ask about this. So here I am. Ok first principle. the setup. let's say we have invented a perfect telescope on earth. such that we can resolve any object no matter...

I'm just a physics lover

I've come here to ask any future questions I have regarding physics, mathematics or engineering. Thank you very much.

TL;DR Summary: In summary. I have BSc in Chemistry with honours and want to make research in more theoritical physics oriented field. I don't afraid the studies and the hours needed but I want opinions for the best possible option (MSc or 2nd BSc), in terms of usefulness for my PhD application...

Hello all! I'm a physics student, planning to apply for a biophysics PhD program once I finish my undergrad. My main topics of interest are neuroscience and microbial communities. Originally I was just in physics because I liked the approach, but statistical mechanics showed just how...

1 exercise: The light at that point will diminish. Explanation: Since the waves are coherent, their phase difference depends on the difference in distance travelled. A path difference of 2 µm is equal to 5 wavelengths (λ = 400 nm). When the phase difference of the waves is 5λ, they are in...

Is the physics down below sound? I always thought the highest momentum is the most powerful. "Biomechanically, humans are REALLY good at throwing things and quite good at swinging as well. When it comes to thrusting we are good, but not as much.But the larger portion probably comes down to pure...

ay = -9.8. Vy = -9.8 + v0*Sin0. y = -4.9*t^2 + v0*t*Sin0. By using formula of y, my solution was -4.9(10s)^2 + (10m/s)(10s)Sin0. I assumed that y was equal to 0. Since -4.9 is m/s^2 the answer would be -490m + 100m*Sin0. Therefore I assumeed Sin0 = 490/100.
