This concept only after crossing earths field , becz in earths field of gravitation ,the external force (gravity ) acts in x direction hence velocity of COM is not constant but decreasing continuously , linear momentum will not be conserved
suppose a rocket moves under the influence of no external forces suppose initial mass of rocket is m' and initial speed is v' exhaust speed is u prove at a later time speed of rocket is v=v'+uln(m'÷m) ? Sir plz solve this numerical
If rocket have kinetic energy more than potential energy on earth, It will leave the earth's atmosphere, that's true. BUT my question is that " If direction of rockets's prapogation towards the centre of earth , then what would happen?
Rockets do not work on the mass principle. they work on the pressure principle. . the mass is irrelevent. If you can create high pressure with less mass , then all the better.
This is false. MOMENTUM is MASS times VELOCITY (P = M x V) So you can get high MOMENTUM with either high mass and low velocity OR low mass and HIGH VELOCITY. A rocket engine expels low mass at REALLY HIGH VELOCITY creating a RECOIL FORCE that pushes the rocket forward. Lets leave the thinking to the people that bothered to finish high school, and not a goat herder with the intellect of a five year old.
@@stuartgray5877 Rockets do not work on momentum. You fool. Rockets work on pressure. ALL rockets create a high pressure area behind the rocket to propel it into the lower pressure area in front of it........the end.

In space not a point where v equals 0
Thank you from tamilnadu-india.
Once In my life I want to meet u sir.
Sir is no more 😔😔🥺🥺
@@67sumansil73 oh no😢😢
@@67sumansil73 really 🥺
Why
Rip sir
You have confused formula sir gravity affects acceleration of the rocket
Sir, I have some problem in understanding the topic , my fundamentals not yet cleared.
That's why I can't understand🎅
Very well explained sir 👏

Momentum of rocket should be (M+m-dm)Vr
sanjai singh mera v yhi doubt tha.......then i see ur cmnt😅
Right
thank you sir🙏 to giving me this knowledge🙏 .
your way to teach the students is really very amazing.👏

Very nice video sir👌👌👌
sir i miss u sir 😥😥😥
love u sir
What happened bro

U are great sir
How 0-dm Vg =dm Vg.in Change in momentum
Sir please Hindi medium k liye bhi kuch kro na ..🥺🥺🥺thoda Hindi bta Diya kro ..
Thanks sir
Thanks a lot sir
Now the sir is not with us he died in 2020
Excellent video sir
Once again repeat the question
Superrrrr
Kuch samaz nahi aaya 😭
I am little confused
