Angular Velocity Physics Problems, Linear Speed, Frequency & Period

This physics video tutorial provides a basic introduction into angular velocity and linear velocity. It explains how to calculate the linear speed from angular speed using a conversion / dimensional analysis process. It also explains how to calculate the angular velocity of a wheel given frequency and period. This tutorial contains plenty of examples and practice problems.

U r literally my chemistry, mechanics, physics and math teacher dude thank you so much for everything

[mathavankrishnan]

After becoming a uni student, I am depending on this guy more than my professor. Man, you are the best !

[jacobmogorosi]

Thank you so much for these tutorials. I've passed mechanics so well last semester and I encourage you to continue your good work. May God bless you for your outstanding way of teaching and give you the strength to do even more! I'm so happy I could dance right now!

[abrahambalamba]

This man is more than a normal teacher

[bodeabbott]

you always seem to make a video that gets to the point and is about exactly what i need to learn. The example questions are usually what I go over In school, but I always come back to this channel because it teaches me everything. Thank you organic chemistry tutor.

[satestactmathtutor]

the way you explain why is radius is meter per radians is amazing nice job broo letting us know the most important thing about learning is the why

[serhatgundem]

In the last question, you only converted the linear speed into the speed with the wished units, but you didn't multiply it by R (since V = W * R). Am I missing something?

[technologyfield]

Bravo man, am passing mah mechanics very easy, may God grant you blessings

[phoebecooper]

For no. 4, to get 14.76 mph, you have to do instead of which would get 38.22 mph.

[lumhoxha]

Woww man you are the best. I learned these formulas perfectly thanks🙏

[CS-etfs]

word can't describe how many time he save my life.

[haydn]

Why do i feel like this guy is some kind of child genius

[vctor]

Even our professors come here to refresh their teaching skills

[gearblader]

I am searching on how to transform angular acceleration as a function of theta to angular velocity as a function of time.
let say that a(theta)= Newtons*Sin(theta), where Newtons is a controlled variable that is held constant. And V an initial angular velocity at t=0.

At 10:01, the question asks for v with a radius of 20 cm, and yet he uses 0.1 m

[CS-etfs]

does he have a patreon version of this

[adityathete]

Ignore all problems as you ignored the diameter in the first question 3:25

[pypersennecke]

I really should just be paying you my tuition

[tate]

You are Albert Einstein reborn, thank you bro

[otakujyanai]

What do u do if your only give a raduis?
