Sir dont stop making videos we all are in support of you I am from india and i hve shared this channel in my scl grp all students of my class says that they had not learnt physics in this interesting way before

Wow I never knew we needed to know some linear algebra for Physics C!

Looks great! (I like how Billy is muttering while Bobby is listing off the matrix elements in the first example.)

I do not understand how the direction of the torque can be in the direction of the rotation axis. Then how can this axis turn around? It hàs to work perpendicular to it.

Sir when we rotate keychain in our finger then why it moves upwards?? I hope you understood my question

If T is defined as T = r x F, and we change r, what happens to T does it stay the same and F changes?

How can you claim that the definition of L = r x p works differently?

What evidence do you need to be able to see the truth?

ahh so the C in Physics C also means Linear algebra, good to know as a Physics 1 student

Sir, I was looking for your videos on electromagnetism. I couldn't find them.
