Ashish you are doing complete justice to the quote of Einstein written on the right side of your white board. You have literally broken down the concept of rocket science into an 8th standard physics and maths. This video is the best video on RU-vid, i can vouch for it🤩😍🌟
I knew the 2nd and 3rd point but all these days I thought it was only Newton's 3rd law that pushes the rocket. Thanks to you for broadening my knowledge.
Thanks sir for all of your help . I have many questions 1. Why we go to space. What are exact benefits of exploration 2. What is international space station. 3. I have seen a lot of fuel burned when rocket leaves earth. Please tell some approximate value of fuel required , type of engines and their working . 4. Difference between rocket and vehicle 5. How it feels inside rocket when it just launched from earth ,as it was having very high speed.
Appreciating things r: 1) editing.. excellent 2) learning the interest of ur audience nd hence releasing the corresponding content 3) trying to encourage to build sci / tech Audience..topics necessary but rarely viewed by smart indians...ofcourse need more videos..god bless you brother....
Sir it's only you who giving exact solution of real time problem faced by any student . I'm also preparing for ISRO but I am from ECE background . I watched your all videos Thanks a lot sir (Kabhi Haryana aao to jarur btana sir)
sir aur aisa video banaoo . because today I was very much surprised to know that even our sun is also moving. felt that our mythology was right even sun is also revolving around something not the earth but something
@@anindyasinha8930 u are falling only under the influence of the gravity....and during this motion u won't feet ur weight under ur feet....(neglect the reaction of atmosphere) But u will feel once u reach the ground..😁
1. According to newton's third law whenever there is a action there is also a equal and opposite reaction If the rocket moves then it is action so there must be a reaction so newton's third law is applied here as well just it is hard to notice because of no visible surface of contact 2. Conservation of momentum is derived from newton's 3rd law so if there is a case where Conservation of momentum is applied then newton's 3rd law can be applied there as well because without force momentum cannot be generated and if force is there with displacement action is there hence reaction too is there
1. Rocket’s action on what? The space? There’s nothing in space to put action upon so there’s nothing in space to put reaction on the spacecraft. 2. Just because it’s derived from it does not mean that it’s the reason. Bernoulli’s theorem is derived from conservation of mass but we don’t say that Venturimeter and Pitot tubes are allocation of the later. Hope it cleared things for you
BRO I REQUEST U IF ITS POSSIBLE U BETTER MAKE MORE VIDS RELATED TO ROCKET SCIENCE. IM LEARNING SO MUCH INFORMATION FROM YOUR CHANNEL THAN I EVER DID IN MY 10 YEAR OF PUBLIC EDUCATION. PLS RESPOND....
maza aa gaya aaj tho . aur main bachpan se bahut faceneted hun astrophysics and quntum physic so about time travelling tho uske bare mein thoda sa please please detail explaination chahiaa and thoda motion of planets and their star ke bare mein bhi batao because today I was very much surprised to know that even son is also in motion and our Earth is motioning along the motionary axis of the sun. and love u aaj sach main maza aa gaya
Sir what will be after sun's escape velocity to go another galaxy and what's the force which makes sun to revolve around the galaxy? Please reply sir I request you🙏🙏🙏
Again got this masterpiece under YT recommendation 👍👍👍👍 Actually I think YT doing me a favor over and over again. 😀 Came here through Torq4712 Btw thanks Man 👍👍👍
Sir as we know we feel weightlessness when we are in orbit and space too. Means whole space( solar system) is falling free in action of some other gravity (not earth's) that is why we feel weightlessness in space ..as like example of plane falling free on Earth in a projectile.. Is my thought is correct ??
Can you explain how spaceX makes their rocket boosters land again on earth after making them reach space. I would like to know what kind of tech do they use for such purposes.
space x currently lands their 1st stage only and that does not reach space. Once the 2nd stage is separated from the 1st stage it falls dows in a projectile path. Spacex then reignite the engine to slow down the 1st stage and then touch down softly.
Sir plz suggest me some u tube channel or link to understand all about rocket science or space to best use my time. I m in b.tech mechanical 1 st year.
Sir please explain nuclear fueled rocket voyager 2 how can it move far places in galaxy by escaping suns escape velocity and please explain more about orbits in space and how the satellites get into the orbit of Mars and moon and can land at the places they are desired to reach? Thankyou sir
It is pretty simple and I do agree with a lot of your points. Though on your first point saying there is there is no force in space to make the rocket fly. Rockets don’t fly in space. They float. They fly upper atmospherex
ashish bhaiya ...u know my chacha is also a scientist at isro ahmedabad....but he never explained me these things.....anyways u told it to me....im ur fan ....(lol) -----> lots of love
Well the thing is I was not amazed I am in now 11th read about 3-4 books ok astronomy I knew these concepts but dude thanks for the effort cause I understood it even more than I could from books and I am obsessed with astrophysics
hey!! ashish sir u explained 2 well bt can you plz explain tht why we feel weightless during free fall.?. I want to be a space scientist like you!! hope you will answer..
Ashish bhai Mene Suna hai ki before escaping or even before entering atmosphere of anyplanet we have to move in some orbit of that planet ? Is it true? If yes then who decides the radius of that orbit ? Is it different for every planet ? What is it for earth ? For moon ? For mars ? And also for sun ? And why we have to move in orbit if we can directly trust out of atmosphere ?
@@ashishranjantalks how is it economical, in orbit we have to travel even more distance na then it becomes economical? And on what basis this radius of orbit changes ?
Hi Sir vedio is very helpful Thanks, I have one doubt, If a rocket is going with a speed of 8km per second and rocket had enough fuel to reach Mars but it can't reach the escape velocity but speed remains same , So now what happens to the rocket????
That's a brilliant question. I think you mean is, what is I can keep burning the engine at slow velocity where will I go... Well you'll keep on orbiting the planet, you won't be able to go straight to Mars
@@ashishranjantalks Thank you sir. it's my pleasure to get an answer from a former ISRO Scientist. Sir I am only 15 years old, but I am your follower and I also want to be a ISRO scientist like you. When India reached the Mars in 2014, I got inspired and decided to be a scientist and your vedios encouraged me. So I am preparing my mind to think like this thus I got this doubt. 😄😄😄
I have more confusion on rocket science when I was watching mangal mission movie.can you please explain about the concept they were used for mangal mission in that movie.can you explain how rocket reached moon with detail.if you will then it will be a wishful thing for me.guys who want this concept plz comment.plz sir make a video.thanks for your knowledgeable information about rocket.
Bro Ashish being in ISRO u could have started a research on rocket science. We would be very happy to know new things, new designs to build a most efficient and powerful rocket designs. By the way I would love to know more about liquid rocket engine and what idea u have on improving it. Love to know ur theories.👍 keep it up.
So can we say that we don't stay in a same orbit or the same position /place as we were yesterday since the motion around sun is spiral so will be the orbit ??
