Physics 9.5 Introduction to Momentum (5 of 9) Momentum in 2-Dimension Explained: Graphically

In this video I will graphically explain how to find the final directions and velocities when 2 masses collide.

Next video in this series can be seen at:

Thank you Professor van Biezen. Just know that your work is seriously appreciated. Because of you I don't only understand physics, I am loving it.

[Alexnt]

Man, please never stop making these videos. Believe me, you help a lot of people, because you teach in a way far superior to other youtubers.

Congrats on hitting 100k ! Your work is very much appreciated

a teacher who made me to understand momentum since i was born

Without your Channel, probably I failed miserably, now I got an A! Thanks

Hello Professor Biezen! At minute 3:17, you say the intial momentum for x is equal to the sum of its components after the collision but you wrote y instead of x. I am a massive fan! Just wanted you to know!

Thank you sir. You teach the concepts clearly and I can understand it very well.

[lachimolalalala]

Thank you very much.
I am appreciate it.
hope you will keep teaching like this.

Is it okay if I insert a negative sign so it looks like this?: V2fy = -V2fsintheta2?

[MriLyn]

can anyone tell me how to find out the angle of these 2 balls ?

[Notra_bel]

3:10 I think that should've been vfx, am I right?

[ahmedal-ebrashy]

SIr I guess there is a mistake. I am not sure because you wrote m1v1=m1v1fx+m2v2fx not fy. If it is a typo please correct it as it is a bit confusing. I dont know if I am right or wrong
