2:00 just wanted to point out, (mainly for reinforcing my own understanding) that the constant of proportionality over here is the force. If the force doesn't change, then acceleration is inversely proportional to mass.
It is clearer to think that acceleration varies inversely to mass, and directly with force. The constant of proportionality would be one using SI units.
Thank you for these videos it really helps me a lot😇 Just one small question: At 06:28, what if the upward and downward force didn't cancel out? What would be the Fnet and how would we write it? For example if the force was 22N in the upward direction, instead of 20N, how would the Fnet be calculated? I know this involves calculating vectors but I was unable to find anything about that on your channel.

Just want to say thank you for making these videos. It's really giving me a good understanding of the material.
Thanks for making this video! Really helped me out for the test.

We would have a vector addition problem. We would need to add the 2N upwards vector to the sideways vector.
Chris Doner oh thank you
You sir are a blessing

what are you using for the drawing
A drawing tablet and the software for a smartboard.
just curious - why was the first video deleted?
I forgot to add the table of contents.
@@donerphysics you can edit the video later and add that in btw
Yes, but in this case it would take longer.
