Collisions - Momentum - IB Physics

There are three types of collisions we deal with in physics: Elastic collisions (two objects bouncing off each other), inelastic collisions (two objects sticking together) and "explosions" (one object splitting into two). To predict the motion of objects after a collision, we use conservation of momentum: the total momentum of both objects before the collision is equal to the total momentum after the collision.

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

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

Thank you so much!! Is there any practice questions for collision with an angle please? Love your work as always.

For all of the videos you make, do they cover HL material as well, or is it purely SL?

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.

what do i use in case of friction involved?
