This comment is not to praise the quality of the teaching, which in no ways is in doubt, but to critique the wonderful look ... On that note, I remember watching your videos long ago, and at one time I wrote, I wish I could get a brain download because I was so frustrated at times with numbers .. seeing you now that you are still doing these videos gives a feel of happiness... Back to the look, it looks really cool... And you sound smarter ...too 🇳🇮 🇳🇮 🇳🇮

Hello Professor, I'm wondering what chal board and chalk you use?

Wait when you had the 15 rev/ min, why did you multiply by 2pi to get angular frequency, shouln't the 15 rev/ min be the angular speed?

Angular speed should be radians per minute, not revolutions per minute.

but isnt 1 revolution equal to 1 radian, so shouldn't it just be 15 rad/ min?

@@jeffreyjames4830 One revolution is defined as 2pi radians in the books I teach from. It takes approximately 6.28 lengths of the radius, 2pi, to get around the circumference of a circle.
