Hello Mr. Masley, I'm watching all of your videos to prepare for IBDP Physics HL, but I'm confused why the red ball before the collision at 15:30 has no momentum
Hi Mr. Masley, I have a question regarding the y-components. How do you determine if it's negative or not? For example, the downwards y-velocity in the elastic collision 2-dimesional problem was regarded as negative 13:45, but in the inelastic collision problem, the downwards y component was positive.
@@AndyMasleyI came to ask the same question - I’m confused on the last one because I made the Y component a negative number so I got a negative velocity. Is that still fine?

Thanks a lot for these videos. Your Explanatory Style is amazing it's pretty easy to comprehend. I really love your channel. Waiting for more videos
Thank you very much Andy!
These videos are wonderful and I like how a lot of example questions are used.
Keep up the amazing work.
Thank you so much Mr. Andy, I needed this
I sow all the video' on momentum that extremely useful thank you.
Would you consider making hl videos as well, it would be greatly benefical for hl students thank you

Never mind I got it
@@lelandwang7596 Yay! For anyone else wondering it has no momentum in the x-direction, but does in the y-direction
really really really helpful !!!!!!
For all of the videos you make, do they cover HL material as well, or is it purely SL?
Thank you so much!! Is there any practice questions for collision with an angle please? Love your work as always.
Thank you sir ❤️

It's arbitrary! What matters is that you keep the negative and positive directions consistent throughout the problem.

@@Judy-zf6dzYup! A negative velocity just means a velocity in the direction you've arbitrarily set as negative.
what do i use in case of friction involved?
please marry me andy i love you
