You have replaced my phys 298 professor. You're the only clear speaking, slow teaching, individual on KZfaq with a nice presentation and solid delivery. This channel deserves SOO much more attention.

knowledge still being delivered even after 8 years of shooting it. Great job sir.

Explaination is so clear. I've never seen it yet in my University! I just attended class to not get denying. Thanks you Prof. I hope you have a happy life.

He has mastered writing letters backwards

very clear, step by step explanations. Simplifying what I consider complex things makes me feel good in class...Thanks Prof

You literally are the best physics teacher on KZfaq and one of the best I've ever gained knowledge from! Kudos sir! Thankyouuu.

Am i the only one who wonders about how he write without writing backward?

Sir u r a highly knowledgeable and highly student friendly person...sir ur lecture made me super expert in solving all the question of jee advanced previous year questions thanks sir..u r great

I wish you were my professor! Thank you for making this video Dr. A!!

You sir, are an angel. Written at 2am the morning of my 8am exam on dynamics and conservation of momentum.

watched for fun, always trying to expand my mind. honestly though the only thing that had me watch to the nd was the fact he was writing backwards and still understood the material enough to present it forward in a lecture type setting. bravo. hope my physics profs are half as educated

very patiently and well explained! Thank you so much!!!!

It looks so cool because it looks like he is writing backwards but it's just the mirror effect I found that out by looking at your wedding ring. It looks really cool. Thanks for making this video.

I needed to watched this video for more than once. I love when he asks the class: QUESTIONS ABOUT THAT? Do they genuine have no questions to ask? By the way thanks for making this valuable content available to all of us!

Such a great video! Thank you so much, sir, this helped me a lot!

Wow, it looks like a glow stick! This video is great! Thank you.

its great your uploading stuff like this.

As a high school student I think your videos are INCREDIBLE great set up with mics and especially the board curious how you did that ;) Love the whole set up you deserve more subs keep it up Professor!

Hi, do you have an explanation for collision where friction is eliminated (like in air hockey)? I was wondering on the effect of friction in collision, and planning to do an experiment on that. Thank you, in advance.

Great explaination ! Collisions in 2D has become clear as glass now !!

excellent explanation with impressive personality,,,may Almighty success u,,,,thank u sir

You made is clear and simple. Thanks you sir

Thank you soooo much sir now my concept is clear. I watch many video about 2D collision but this is video is bestest ever. Thank you sooo much Sir again😇

Sometimes I feel frustrated when looking at questions involving many linkage between equations or messy. Ur presentation is very neat, I understood easily.

I understood perfectly, thank you so much!!

you're a life saver...Thank you a lot.

your handwriting is therapeutic

Very good explanation :)

Like if you watched this during covid online classes

Hello matt I m your fan way of explaination is good

Excellent 👌

the swag n attitude of physics is next level👍🏻👍🏻👍🏻👍🏻👌

I get it but its also a very tedious process, thanks for the clear explanation Mr Anderson, swagger video

wow excellent presentation

Perfect explanation! thanks

Great job!

Abdul c'mon bruh

I am amazed of his level of inversed writing

thank you sir for explaining the concept :)

Amazing session 😁😁

I wish you completed the answer. I understand literally everything up until what you showed, but am struggling with actually solving those angles

best lesson ever I see at this topic,,bd

very nice i think the negative sign is due to momentum is a vector quantity as it have both magnitude(size)and direction .i am i clear?.

This is the perfect method to teach in 2020 pandemic

Hes a fking genius

Thanks sir, really helps

You just saved my ass today.im writing physics and after this clip,I'm definitely sure I'll kill it.👌🏼👌🏼👌🏼

thanks from Indonesia🇮🇩😍

I have a specific question of the part when you asked "your student" about P2ix. I just don't understand why it is zero. Thank you.

you cleared my concept of 2d momentum but you confused about how you were writing like that?

Where do you order a board like that? I basically a glass but how?

super explanation

Thank You So Much ❤️👍🙏

Thank You sir..........

Maths anytime, physics like a shooting star

Thank you so much, sir

Wait i have a question, what sort of whiteboard is used in this video?

How do you write on that glass?

Thank u MacGyver

Is he drawing everything backwards on glass so it looks normal for the viewer? That takes some skill (in addition to knowing the physics/math itself).

Anyone else felt bad for him when he asked questions and checked if everyone was understanding and no one answered

Thanks, Dr. A that helped a lot. I was kinda nervous because I didn't understand the material very well.

i want to love this video

youre waffling

Very good explaination

love ... 😻😻 thank you

Better I should say,"PERFECT!"

Bravo!!!!!

great !!! love it :) now do with with vectors :)

I think the assumption that the two cars stick together after collision is incorrect

Very good.

i have question, why on y direction have you took horizontal direction as sin x

Any idea where I could find material for how to collide 2D objects that have rotational parameters as well?

So good

Sorry I have a question... What if the car don't stick instead collides and travels seperatly to two different directions????...... Am asking this cause your formular for collision on the x axis is contradicting my text book and google tbh

Respect to you Professor

You can use hieroglyphs to illustrate, and better understanding. Thats what i do and soon, come à publication.

he :teaching me:how is he writting on the MAGICAL BOARD?

The only thing i couldn't find an answer for : is he writing from right to left?!

Physics test in two day. I can feel my gpa rising :)

how are you writing backwards throughout the whole explanation?

You can also solve this problem using the conservation of the velocity of the center of gravity. In this particular problem, the initial center of gravity will be at a point in the 3rd (or 2nd) quadrant, on a straight line connecting m1 and m2, but also on a straight line connecting the origin. Notice that the COG point will always be at the fraction m1/(m2+m1) of the total shrinking distance between m1 and m2, away from m2. If you connect this initial center of gravity point with a straight line that passes through the origin, the COG point will always have the exact same velocity vector on this line, before and after the collision, passing right through the origin and into the 1st (or 4th) quadrants. It is very interesting (at least to me) to solve these problems with both conservation laws.

all douts cleared, by the way what are head on collisions ?

pay attention chris.

I wish u could be my professor

Deepest condolence to Abdul Aziz

what if 3 cars collide?how to calculate?

Sir how r u writin from behind so that we could see it correctly r u writin in opposite way kinda???

Amazing explanation!!

Man what university is this so I can transfer here to get a good professor for Engineering ?

He wrote p2fy instead of p1fy. Great video though

Chris look alive bruh

I fuking want that Marker

YESS I GET TI BRAH PLS

I was literally waving my arm at 8:26 😂😂

I wish he used numbers tho.

How are you writing in air?

@mini heart attack @5:33

Am i the only one who finds him painfully attractive?

you are amazing and I like the explanation but I can't stand the annoying noise that comes from the marker and the board.
