im more impressed of how he writes the opposite direction just so the students can read , or there might be something with that glass.. idk great video though, thanks.
Thank you for this videos, are very helpful. You are making a very effective way of teaching! You had already helped to guide the path to thousands of future scientists. Wish you well, Matt.
Hey Professor A, I'm a little confused uniform circular motion and nonuniform circular motion (just went through your videos on those two topics). Perhaps I'm not making the connections between some fundamental concepts and circular motion. In uniform circular motion, velocity -- though changing direction, has a constant speed. So if I were to plot an acceleration vs. time graph, wouldn't a=0? So how is there acceleration during uniform circular motion? But let's just assume that I totally understand that uniform circular motion does have acceleration. So now I'm wondering, how does this differ from nonuniform circular motion? In nonuniform circular motion, since velocity is changing speed, acceleration is present. In both cases -- uniform and nonuniform -- we have a change in velocity, and therefore a change in acceleration. Why are they different? How does a change in direction for velocity differ from a change in speed? Thanks so much for your time, and for these videos. They are super helpful!
Kelsey, Good question. Since acceleration = change in velocity, there are a few possibilities: Speed changes but velocity direction = constant ( -> linear motion), Speed = constant but velocity direction changes (-> uniform circular motion), speed changes and velocity direction changes (-> non-uniform circular motion). Hope this helps. Cheers, Dr. A
I got a question on this. For non-uniform circular motion is the centripetal acceleration not constant because the speed changes because of the translational acceleration so when you put the speed in the formula v^2/R, you will yield a different centripetal acceleration because v is not constant. Thank you very much.
The centripetal force is the net force that keeps it moving in a circle. For a vertical loop, at the bottom the centripetal force = T - mg. At the top the centripetal force = T + mg. Cheers, Dr. A
Victor Maxwell Peters, v is the speed. Thanks for the comment, and keep up with the physics! You might also like my new website: www.universityphysics.education Cheers, Dr. A

It's magic bro. Magic
Thanks. But it's not magic, bro. Just a bit of optical trickery. Check us out here: www.learning.glass

I figured you weren't wrong-handed.

You just earned a new subscriber. Keep up the great work!

Mr. A doesn't get that much love for the content he creates... I'm studying this because my teacher can't teach and we have a quiz tomorrow!
Hii
the way he writes is really cool . awesome . his way of explanation and derivations is great too .
Thank you. Keep up with the physics.
Cheers,
Dr. A
what a concept . thank you so much sir

Thanks Professor A!
thank you professor i had a simliar question on my home work and the video really help me thanks alot for you work
Excellent. Thanks for the feedback.
Cheers,
Dr. A
can you sir also upload angular frequency vs angular velocity.
I got a question on this. For non-uniform circular motion is the centripetal acceleration not constant because the speed changes because of the translational acceleration so when you put the speed in the formula v^2/R, you will yield a different centripetal acceleration because v is not constant. Thank you very much.
For non unifrom vertical circular motion of an object tied to a string, would the tensino force only depend on the centipetal force?
The centripetal force is the net force that keeps it moving in a circle. For a vertical loop, at the bottom the centripetal force = T - mg. At the top the centripetal force = T + mg.

@@yoprofmatt Thank you so much :)
Good derivation . i like it
Thanks. Keep up with the physics.

Konuyu çalışmayı bıraktım, tersten nasıl yazabiliyor onu düşünmeye başladım

From were did ' V ' poped out???
Victor Maxwell Peters,
v is the speed.
