@Downtown Gamer👉 right bro
I am from class 9 but also I am watching your vids☺️☺️
Love your vidoes
Sir, your teaching way is very best, because you teach according to student, a null student also can understand your questions.
Sir thank you so much
The biggest quality of a youtuber is that he never asks for subscribers...... and this quality is eminent in Mr. Alakh Pandey
I was thinking toooooo.... 😎
Because of this he has 1.2 million subscribers
Legends don't need to ask for subscribers
Yaa right bro .. kabhi bhi ye nhi kahe h subscribe karne ke liye ...
Truly said bro
Thank you sir, 😍 Apka channel 1 din bohut bda hoga dekhna

Not only one of the best teacher.
But also the best teacher of physics on You tube is sir Alakh Pandey
U are right bro

Such a change in education.
Thanks sir .. I really feel that from when I started seen your video physics is very easy . 👍 Thanks sir , you are the best teacher.......

Sir my exams are after one month and just started to watch ur videos from yesterday i didnt had to rewind for once everything is clear like water love and respect from Bangladesh 🇧🇩
I just got admitted to class 11 one month ago , after attending some classes of physics at tuition and self studying i found it to be the worst subject, I did't get any topics.But after following this lovely channel, i got interest in physics. This teacher is awesome.

Imagine my condition, I tested positive for Wuhan virus and skipped one month of online classes
@@adityarajsrivastava6580 many have gone through that
hope u are well now
Same here bro. I don't understand what the teacher is teaching in the tuition of PHYSICS. So, I don't concentrate on the class because even if I try to understand what is teaching, the teacher is so fast , bad and skipping important parts that I don't get anything. Hence, I stay chill in the class and learn all the concepts from Alakh Sir. He is true gem
Are u now in iit??
An awesome physics teacher is hard to find difficult to part with and impossible to forget
Thnqq sir. I can easily understand ur all lectures 🙏🏻🙏🏻
Alakh sir toh acha padha hi rahe hain and that's great, but the comment section is fabulous too because you people solve each other's queries! I'm so glad, an applause for yourselves please👏👏

2024 janta......🤚 attendance here😊
hi friends , there isa channel named physics linx .pls go through that channel content 100 %. that sir is delivering the contents so great so student community has to he lp him
I am from Bangladesh.But I am really greatful to India for this type of educational channels.
19:06 bhai is question me angle kahan hai? wo to consider hi nahi kiya
@@smoked8471 Cause he used i,j,k form to find dot products of vector. There are 3 forms of vector for example
3i+2j+5k (unit vector form, idk what's the exact name but i am calling this unit vector form)
(3,2,5) ( coordinate form)
(38^1/2) at any angle. (magnitude and angle form)
We use angle in the last case. Sir use the first case to represent vector therefore normal multiplication worked. In coordinate form we use matrix multiplication.
This might be not totally accurate but it should give a rough idea.
