Rocket science itself isn't Rocket science

Lol

that'd be a cool problem. I might do that as a separate video, thanks for the idea!

I was thinking the exact same thing 😅

Haven't calculated the answer yet myself and haven't reached the answer in the video either, but the time it takes should be short enough that the change in g would be negligable considering even on the ISS the gravitational acceleration is still around 90% of what it is at the surface. EDIT: Guess I was wrong with my guess of the time.

@Dalroc well, considering that every gram of payload costs a lot of money, i'm sure companies like spacex take this factor into their calculations. After all, if g gets weaker with altitude, less fuel is needed.

hello, what would you recommend me which AP physics class (should i take) is paramount to get in to top 10uni in the world. like harvard, mit , oxbridge

I'd recommend AP Calculus and AP Physics, the calculus based course. I'd also focus on learning as much physics as possible, you can have a fantastic undergraduate degree at so many universities and be extremely successful. You got this, good luck!@@EdisonvsTesla

@@zhelyo_physics i appriciate it.

Let's goooo!

Thats how physics works

Mathematics is the language of physics. It usually works this way.

Physics is mathematics:)

@@bluefirephoenix397 The AP Physics exam bro 💀

@@firefx963 idk what that is I'm only grade 12 (STEM student) 💀

Thanks! We practiced, although it might be fun to attempt an Olympiad without practice. It'd definitely be a long long video filled with lots of thinking. Stay tuned! : )

Press arrow up

Well Newton's 2nd law of motion says that: F=ma And F refers to the sum of all forces exerted on the object.

@@abderrahmanekharfi8489 F = ma assumes a constant mass. Really, F = dp/dt, where p is momentum (classically, and non relativistically, p = mv, and if m is constant then dp/dt = ma).

Yea the whole thrust concept and derived formula is covered in NLM

You're right, my mistake. In writing this down as we filmed this part of the video (I think I was just too excited with the problem) I forgot to write in the 2 - but the calculated value is correct.

oh great to know, I might redo it, thanks for letting me know!

It is.

thats a good idea, but isn't JEE a mix of chemistry maths and physics?

Yes, I made a mistake writing it down because I was so excited by this question - but the answer is correct!

jee

Yes in JEE centre of mass…variable mass system

@@dhruvacharya2602 it was really hard to understand but here i learned a better approach to those com questions

Well jee student have almost same knowledge as mit 2nd year student who is just opting physics as minor

​@@Ayush-yj5qvreally though? The quality of education and infrastructure of mit is vastly superior compared to iit

hmm, thats if you consider the rate of change to be inconsistent with respect to time. Else, u could use this equation, and find a relation between the rate of change of mass with time at any instant and then solve the question. Since the fuel velocity is constant, d(mv)/dt, would just yield dm/dt*v using product rule and then use delta instead of del for thisequation since dm is consistent with time.

These are for A Level Physics students

Yes. But dv/dt is 0 because velocity of exiting fuel is constant in the rocket reference frame which essentially boils down to what was done in the video.

Yes bro , first question is of variable mass which is taught inNLM in 11th

Bruh, these ones are easier.

🤣🤣🤣 as a JEE aspirant, JEE Questions are 0.1% of Olympiad Questions. If what you are saying is correct, why hasnt India consistently achieved first rank in IMO, IPhO, IChO?

Quite simple actually because Indian students have to handle all three subjects physics chem and math while preparing for iit jee which is what most students who choose science do and hence can’t go all in for one subject and the math in imo is completely different than in jee but still many Indians do well in olympiads and a lot of the times the top rankers have gold medals in some olympiad

kuch bhi mat bolo bhai olympiad level problems jee advanced me 1% aati hai

T=0 means weight of fuel+ rockets weight..as no fuel is lost at t=0..the mass will be maximum

And the mass decrease as time increases bcz of loss of fuel

Yes :)

bhai mene suna JEE ke questions diye

​@@srveer2883Ha mains ke kuch questions the. Ek case based study ka question tha wave optics ka Jo BSC 2nd year ki book se aya hua ha 💀 Mene zyada pdha nhi tha saal bhar, last ke 15 days ma hi pdha tha isliye zyada kuch nhi bolunga, but difficult to tha.

I have so much fun solving them. They typically involve original solutions or thinking which are not commonly found in textbooks. The answers often deduce to showcase beautiful relationships. I also think they are more applicable to physics at university.

How

Bro there are some easy question in jee advance also but 2 and 3 question we somewhat like jee advance.

Not all the Olympiad problems are super complicated - lots are great for all A Level students.

@@obamabinladen2206 my comment is just a joke about the Indian always yap about how hard their education system is whenever there is a video about education. (i’m not an Indian btw so i can’t answer your question)

so not the person you replied to, BUT, you exaggerated a bit with the percent part they each have some very excellent conceptual questions and he is just some guy who doesnt even studies and just likes to take pride on other peoples achievments or hype @@obamabinladen2206

This one took a while to explain - but I agree that if you took that long to find out where the plane was it would already have changed position again!

Mr Grumpy

that's not the point of the exam, it's an exam testing for physics understanding. The problems are simply there to make you apply physics concepts. They aren't testing your radar plotting skills. The ones giving these tests will go out and build the mechanics of aviation so they must have the physical understanding of its working. The same clarity isn't necessary for a pilot on board.

@@supersomething3979 The exam poser should therefore consider the context of the question. I have had numerous Cadets come on board a vessel and try and apply what they have been taught in teaching establishments how to compare the theoretical Azimuth of a celestial body against an observed optical gyro bearing of the body to derive the "Gyro Error" but the cadets were completely ignorant of the fact they were measuring the optical bearing from an unstable vessel in a seaway using an instrument that at best, on a calm day in port, could measure the accuracy within ½°. And yet they would record the error to three decimal points!
