I genuinely love your video style so so much. I find it incredibly hard to read and focus on written notes, but your way of presenting is so clean and perfect for me I cannot begin to express my gratitude. I will definitely share this with anyone I know who needs help with the topics you cover. And I have my notifications turned on to see other topics you'll cover as well as I genuinely find your presentation very intuitive.
It was a great video, but I have issues with it. How did we get the initial mass? Is the initial mass the mass of the satellite and the mass of the fuel? How do we know how much fuel we need? For example, if we were going to put a 10-kilogram satellite into orbit 400 kilometers above the surface of the Earth, how do we know the amount of energy required without knowing the amount of fuel we need in the first place?
Yeah it would be. When you move closer to the Earth it is favourable in terms of gravitational potential energy, as you do negative work to move it closer. GPE is negative inside the escape point, so it will get "more negative" if that makes sense?
Wonderful explanation, I don't think I will do any question of this topic wrong again.
Thank you
Glad to hear that, best wishes to you

I'm so glad that my videos are helpful to you! There are many ways to learn and I enjoy making these videos to help others.
this video is powerful bro
Thanks, glad you like it
Thank you so much sir.
This is really helpful
You are most welcome
thanks
Welcome!
U are a scholar
I like the way you derive the formula
Really nice
Thanks so much and best wishes

Nice bro keep it up❤
Thank you, I will!
Loved it❤❤
Thanks!
Excellent video as usual thank you
Glad you liked it, thanks to you too.
Thanks!
You bet!
Amazing videos! please make videos about Gravitational potential too
Have you seen this video: ruclips.net/video/z3ujg_CkslI/видео.html
@@stepbystepscience yes I have
@@ranonymous27 Was it what you were looking for?
@@stepbystepscience yes, the explanation was great, thank you very much
Thank you so much. All my concepts are clear!
Great to hear! You're very welcome.
the formula for work is not applicable if velocity initial for satellite is zero because kinetic energy 1 will be zero
Why do some textbooks cite work done = change in GPE, when you have stated work done= change in total energy?
Both are correct, in the video I was also considering kinetic energy.
You can use W=∆PE when it is given that satellite's orbit was changed without causing any change in velocity or very slowly.
quick question sir, if you are bringing the satellite closer to earth instead of away would our r1 then be the greater value?
Yeah it would be. When you move closer to the Earth it is favourable in terms of gravitational potential energy, as you do negative work to move it closer. GPE is negative inside the escape point, so it will get "more negative" if that makes sense?
A: I have difficult to accept the KE=1/2mv^2
B: Why is there the 1/2?
Good question, here is a page that discusses the derivation of the equation,
