Alia, I'm a 57 year old granny with a high school education. I also have pesky leukemia. The chemo Is making me forgetful and...dumb. Last year, I began a mission to understand physics. When Quantum Entanglement won the '22 Nobel, I was hooked. Algebra came back easily. Then, so,much harder. I decided to begin by understanding and documenting inertia. Today, I found you. I can see that I'll be watching everything you've done, pen and paper ready. My husband is an aerospace engineer, but I want to do this alone. With your help! Thank you!
Hey there. You took the reciprocal inside the log without taking a negative sign out. The reason why the log gave a negative number in the first place was because you took dm = delta m but in fact dm = - delta m since the rocket is losing mass. To provide more clarity, dm is the small change in m right? i.e., dm = final m - initial m and since final m is smaller than initial m, dm will be negative. So the differential equation will be m dv = -u_e dm and now the log will give u a positive value.
I think she did mention that it was a negative value but glossed over it a bit, but thanks for your input as I was lost at one point and I found your post helpful.
I appreciated the video, you success to explain us a complex concept with simple words, your pronunciation is excellent, your voice is pleasing and your presentation well structured
A great explanation. Going to watch the video a few more times ..to get behind the math ..and, to hear you say trajectory again 🙂🙂🙂 Love your lectures 🙂 Thank you 👍👍👍
Thank you for your video,it is very use full to me can put the video about space technology, about books ,like cources of future space technologies and also Rocket technology and futuristic technologies in space science ......
Thanks Ma'am for the simple derivation of the rocket velocity eqn. But I notice at 10.36 min, you get a logarithm of the mass ratios (m_2/m_1) which is negative, whereas on the RHS we have the difference between the Final and Initial velocities of the rocket which = negative qty. You have flipped the final and intial mass symbols conveniently, to make the logarithm positive- but is this correct- as the math should tell you what the results will look like, isn't it? Could you please explain this please?
* I meant the LHS (left hand side) of the equation which is the difference in the rocket velocities between points 2 and 1 (V_2-V_1) Sorry for the error
America's perspective on history has been similarly slanted regarding all other countries in all areas of achievment. In school we all learned of Lindbergh's record solo flight across the Atlantic. No one that I knew except for my parents was aware that the British were the first to fly non-stop across the Atlantic (Alcock and Brown in a Vickers Vimy).
Namaste Aliya mam , I'm doing course PG diploma in Aerospace Technical Publication & I also like to share my syllabus (pdf) .. do have notes of this subject (technical publications standard) and also do you read this subject in your semester..
First digit describes the maximum camber as percentage of the chord. Second digit describes the distance of maximum camber from the airfoil leading edge in tenths of the chord. Last two digits describe maximum thickness of the airfoil as percent of the chord.

So... I don't know why I kept saying velocity instead of rocket 😂
Thank You i needed this for a project worth 30 percent of my grade!
Mam, you don't know how much knowledgeable your videos are! Please ,please don't stop making videos like this ever..🥺
BTW sorry for my bad English.
The best explanation that I've seen on the rocket equation. Well done!
Mam please bring more lectures.
Your way of teaching is best.
I love your accent...... you have such a beautiful voice
I found your teaching style awesome and helpful to understand better. I hope you would teach us with explanation as much effective as you can
Love your videos ♡♡. I switched from watching TV series to your videos 😂. I hope you can post more often :)
+1
I appreciated the video, you success to explain us a complex concept with simple words, your pronunciation is excellent, your voice is pleasing and your presentation well structured
I was curious how to pronounce "Tsiolkovsky", and I am happy to have landed on this page! Today is Tsiolkovsky's 164th birthday!
Sep 5 is celebrated as teachers day in India
And u r my teacher
.... Happy teacher's day 😊
A great explanation. Going to watch the video a few more times ..to get behind the math ..and, to hear you say trajectory again 🙂🙂🙂 Love your lectures 🙂 Thank you 👍👍👍
Thank you for watching! And glad to be helpful.
You are really good at what you are doing. Can't wait for another video
Miss please keep on making videos... its soo interesting and well explained 👍🏽👍🏽👍🏽
May Jesus bless u with Good Knowledge sister and keep continuing these aerospace videos.
hello aliya... these videos of u are very useful for me in my undergrad, can u continue the propulsion playlist please.
Please continue to post the planned videos😣😊😊
Lady, I'm your fan from now on.
Hey! I'm watching all your videos and it's real helpful for me, please carry on making new videos on aerospace. I'll be watching it all. ;)
Just wanted to say, you are super good and awesome ;)
Very well explained!
so happy i found this channel!!!!
Thank you for this wonderful explanation
I just watched your 6yr old video you look soo changed your 1st video was nice explaining aeronautical engineering
Thanks! People change))
Thank you for sharing this knowledge with us!
Pls do keep it up...my son learns a lot from you
Thank you for your video,it is very use full to me can put the video about space technology, about books ,like cources of future space technologies and also Rocket technology and futuristic technologies in space science ......
You literally learn about Mendelev in grade school in the US, but in common parlance we just call it "The Periodic Table".
Thank you for making this, I understood it very thorougly
Thank you aliya. it helped me a lot.
i love the videos! Thank you so much
Ty
Thank you so much mam
Very nice explained thank u so much
Hi, Aliya! Excelent vídeo.
Loved your voice, going to use your videos as my morning podcast haha.
great vid, hope to see some new uploads in the future
Thank you Aliya, I enjoyed it a lot. 😊❤✌🌹

How she easily fliped m2/m1 to be
m1/m2
without using any math rule ?
Could you please make a video of rocket equation when the rocket is within atmosphere and gravity is acting onto it.
Put the video soon about the space books...😊😊
Trust me, if you will teach in my University, I'll be the topper.
More videos please
Why your videos has been discountinued? you explain everything very very well
Well done mam!!!
thank you!
Wow so simple tnx mam
Very interesting
Hey, a big fan from Brazil here, why u stopped posting videos?
Do more videos love u
Tsialkovsky...........finally gets credit ...
Ничего не понял, но интересно!)) Спасибо!
I am lost, how come you can switch m1 and m2, in the logarithm?
Make more vedios love from india
thank you !!
By the way, please keep uploading.
Please do other videos
Still waiting for new videos, it has been 3 weeks. So u owe us 3 videos right?
Why did you stop uploading videos?
Shouldn’t the Brit be credited over the Russian, on account of his developing the equation 93 years earlier?
Hello.I need video about takeoff level
Hello, what is the ideal equation that includes all the forces affecting the launch of a rocket into space.
and thank you for every vedios
From which university you did your Masters in Aerospace???
What is more complex aeronautical engineering or aerospace engineering?
I want to study rocket propulsion course of undergrad level in aerospace engineering, are you going to cover whole course here?
From which unversity you have done your aerosapce engineering

Sorry for the error
I think u_e already has a negative value b/c of its direction. Negatives would cancel each other
so what really happens at least I think is that there is a negative in front of the dm as it is decreasing. This means it results in ln(m1)-ln(m2).
Hi I want to connect with you. 5th edition of FoA is good? Since latest on is the 6th edition tq
Since getting you masters degree, have you had any luck getting any internships/ jobs in your desired field?

Hi, I'm an aerospace engineer
Can you explain the Kutta-Joukowski theorem in aerodynamic?
Thank you
please do the derivation also and explain it
I really need it.
your videos are best for aerospace engineers
1:20 NASA fairytale spacecrafts can't even leave their launchpads.
Mam I'm from India
Can you please help me
You are really good explanation about the concepts I hope your are reply for my comment , sure can you put the video of my comment in the comment box ..👍👍👍👍😊😊😊
Me who plays kerbal space program: ohhhh that's what that means
😂
😂👍
What happen as you stopped making videos
I have switched to commerce as science was not my cup of tea
thank you for your explanation and your freaking cute
Naaaa its just the rocket equation
oh so you're dead now right, CUZ IT'S BEEN 6 MONTHSSSS!!!!!!
Maam good day, are you married already?
слушай, а зачем по-английски, говори по-русски
