IGCSE Physics Revision: Unit 6 Space Physics | for Cambridge IGCSE 2023 Syllabus 

Thank you btw, deeply. None of us, students, can show how much we're thankful.

accretion model: 25:35 life cycle of star: 37:25 redhshift: 47:59 cmbr: 52:49

The only video on yt that explains space physics for igcse in the best way possible

Just got my results n I got 91% Thank you so much for all the videos you have made. They have helped me built my foundation level from not knowing what does force mean to me getting A*. For those taking Physics IGCSE, I can guarantee the best if you watch this guys videos

Thank you so so so so much! No one (not even my teacher even though he tries) can make physics as easily understood as you do!

BEST PHYSICS TEACHER EVER!!!

to the people that are taking the exam in the future, 2023 mj was unarguably the most stressful session, new bio style questions, space phy, organic chemistry in the test and the shitty timetable

Thank you so much sir, I got a* in physics in this June series. You are the real hero for students like us and you are literally the best physics teacher I have ever met. I am so lucky to find this precious channel before my exam days and I can’t thank you enough. Waiting for the A level lectures!

Thank you sir! I just got my marks back and I got 95% which i can entirely thank you for...these videos were grade savers...literally.

18:33 ; Here u said g depends on mass ie: g is directly proportional to mass. But Mass is inversely proportional to the gravitational field strength, so if mass increases, gravitational force decreases. g = k/m ( g ∝ 1/m) wherein k = weight.

Hello Mr Mo Ali, just finished my IGCSE physics paper. Thank you So much for helping us students with all the chapters!

I wish you could make Alevel physics videos as well 🙏 ..... it was because of you that I got what I got in IGCSE 🙏

2:27 i Really appreciate this part, thank you very much because you are sticking to your believes >

you are genuinely such a good teacher!! Loved your puns throughout the video :)

YOU ARE ABSOLUTLEY AMAZING THANK YOU SO MUCH i was struggling to understand this topc but u summarised it like a god thank you keep up the great work my exams are in 60 days and im trembling at the tought of it ill edit this comment and tell you how it went in about 2 and a half months and another edit once i get my results shooting for an A* (im doing GCE which is similar to IGCSE but little different ) Jazakallah kair

first time not hating a physic tutorial video. it is just so much fun, nice job

Sir, firstly thank you soooooooo much for all thi videos, i went from a B to A*! Secondly, please can you do such videos for A level, especially edexcel , I really need you ! Anyways Jazak Allah Kheir

You were so helpful in igcse now that we are in AS we highly need your help as soon as possible please

Hello Ali Sir, you have my deepest of respects and thanks, truly nothing can describe the magnitude of your generous and kind help. I had written my IGCSE exam in 2023 oct/nov. I bestow my A* to you, you were not just a teacher but an inspiration. Thanks to your passion and love I have taken the courage to pursue this subject as an A Level subject, something which I never imagined myself upholding. I humbly request if you may further expand your beautiful talent to A Level students as well, you were the lamp in one of the darkest times. I hope you remain illuminated with the same if not increasing intensity in the future I hope my comment reaches you amidst the sea of love you have accumulated from your beloved students.🤗

BEST TEACHERRRRRRRRRRR thank u so much sir for these videos, cant even describe how thankful i am

First time here ..Finished and understood the topic in just an hour.. iam so subscribing here. Im here to stay. Got my finals in October 2023... thanks u. Dont know how l can possibly thank u mehn.

I have been searching for physics teacher on RU-vid here BUT Today God make me to get you 🙏🙏🙏

This video was a literal lifesaver

Thank you soo much !!! Your videos and explanations are unmatched. Please please please 🙏 can you do AS and A level

Thank you so much for giving out alot of your time for us,it helped me alot

ربنا يكرمك. You are my and many others savior

Finally! you're back!

thank you so much for this lesson .....it was so interesting and fun to learn because of the way you teach 👍

Thanks Mohammed Ali Sir! U really helped alot explaining this chapter. I appreciate your teaching. Thank You! #bestteacher #keepteaching #physicsteacher #learnwithfun #liveclasses

Wallahy top el top

Best explanation of redshift

Oml u don't know how happy i was when i see ur notification u r my fav teacher and best ever keep going man!✨

It would be perfect if you made videos like this about as and a level physics

I have my exam in 2 hours and my teacher only taught the life cycle of a star, this video helped ALOT

life saver, scored A* strictly because of this guy

Understandable teachings and moreover loved the jokes in the middle of lecture😃😂

Thanks alot top G, 🙏🏿🙏🏿.

The way he passionately teaches the subject makes me wanna listen to what hes saying. Than you so much sir

this man is a legend.

51:25 - 52:00 Best Explanation of Redshift 👌

lets go guys!!!

love you hogya

Thank you so much P4 exam tomorrow 😭😭😭

Thank u so muchhhh

sir please share the pdf of slides

The man, the myth, the legend, istg you save us god bless you 🙏🏽🙏🏽

51:30 love the class 😂

one of the best teachers helped me alot with physics

there was my preliam 3 exam(MCQ) there was the question about what can be determined from the light from the supernova i ticked distace option but i got it wrong, i talked to the teacher about it is said the answer was speed. She checked the ms it also showed speed i dont know which paper was the question from.

Space chapter is really a beautiful one.

Thank you I got an A* in physics due to your videos

tip: play interstaller space music while watching it, also thank you aloot

i love ur vibe

big shout out

thank you so much, by the way can you please please solve the specimen papers please

thank you so much 🙏🏻🙏🏻 all your videos helped me so much 💗

Please please do these kinds of videos for every topic! Thank you for this!!

Lifesaver!!!!!

the fact that im watching this 5 hrs bfr my igcse btw thank u so much this is so helpful

thank you so much this was actually extremely useful!

Thank u sir

Thank you so much! Btw, why is CMBR microwave radiation of a specific frequency observed at all points when it originates from redshift, shouldn't it be decreasing in frequency as the universe is expanding?

This video really helped me a lot. Thank you so muchhh

THANK YOU

thank you for this vid! you make me love physic again and i decide to choose as physic

PLEASE MAKE MORE VIDEO LIKE THIS ON THE AS- A LEVEL CONTEXT

MO ALI I LOVE YOU RAHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHH

Big thanks to you brooo the paper was soooooo easy

Bro came in clutch lets gooooo

LITREALLY THE BEST TEACHER EVERRR 🙌🏻❤️❤️❤️

Thank you so much sir, my exam is tomorrow and this was so helpful

Love you man ❤❤❤❤

I thank you for uploading such videos. It has been really helpful for me

thank u sm sir🙏🏻🙏🏻🙏🏻🙏🏻 u r the goat💗💗💗

Thanks very much for adding a very useful summary of the new topic for IGCSE Physics 2023 exams. But I have to disagree with your explanation of what causes the seasonal temperature changes between summer and winter. The differences in the distances between sun and the northern hemisphere vs. southern hemisphere is insignificant, and is NOT the main factor. Another common misconception (but not in your video) is that the elliptical orbit of the earth (147 x 10^6 km at perihelion vs. 152 x 10^6 km at aphelion) is a cause. This 3% difference is insignificant, compared with the true causes. The actual cause of seasonal temperature changes is the different incident angles of the sun's rays striking the northern hemisphere vs. the southern hemisphere, because of the tilted axis of the earth as it orbits the sun. This causes the i.r. radiation energy to spread out over a larger area on the earth's surface in winter, compared to a smaller area in summer. (Experiment: shine a narrow beam flashlight onto a piece of paper perpendicularly vs. at an angle. Note the difference in how the same light energy spreads out over the different areas.) Another causation factor is that the i.r. rays hit the surface for a shorter time, during the shorter daytime hours of winter. So average daily temperatures are less in winter. But overall I appreciate your contribution to this new area for IGCSE Physics. Thanks!

I’m not taking physics a level, but thanks to you I achieved an acceptable 8 the past November

Thanks so much

welcome back!!!

Finally yay the legend is back

Thanks again

why don't moons just orbit the sun as it has greater gravitational pull?

All my space physics doubts have been solved because of you sir . Thank you so much.

When are you gonna upload your new videos!! you’re the best teacher ever

Thank you so much for this video!!

32:00

Million thanks for the great deed sir! well taught.....Gratitude from Sri Lanka!!! YOu are blessed for teaching....We are blessed to learn from you sir!!!

this dude>>> wallah ur the best

watching this made me wanna rewatch interstellar

My- Mercury Very- Venus Educated- Earth Mother- Mars Just- Jupiter Served- Saturn Us- Uranus Nine- Neptune Pizza- Pluto

Nice to see you back sir!

When you says tidal wave, i only can see the lyrics of a match into water. It's fun to watch your video btw

Thank you very much

if a star is moving away from earth and when you found the age of universe by star by hubble constant and according means to we are stationary because we don't know the point from where the universe expanded

mohammed ali you’re an actual goat, i’ve been looking at your livestreams for physics

I LOVE YOUR VIDEOS THANK YOUU

thank you so much Jazakhallah Khair

I wish he was my physics teacher
