Physics 9 Conservation of Energy (11 of 11) Motion in a Vertical Loop

[@LawZist]

Best teacher in the whole world! love your vids !!!

[@mubasshirahshaikh8630]

best explanation

[@ahmedal-ebrashy3691]

Npw that am done with the conservation of energy list. I must say that was a lot of work,

[@MELLY_N]

your videos are very helpful🥰😪

[@MichelvanBiezen]

Thank you. Glad you find them helpful.

[@hunters9048]

Are you have any course on aerospace engineering

[@yosefabraham]

Thank you sir you help a lot!

[@denizsesli7068]

saved me from getting ff from the midterm

[@jimmiriarty5799]

Sir how can they have kinetic energy and potential energy at the top?

[@MichelvanBiezen]

With the tension = 0 at the top, the object must still be moving.

[@Shaunss]

If you read this comment, thank you for the concise video.

[@MichelvanBiezen]

We appreciate your comment

[@akashhera]

I got it! Thanks a lot sir

[@MichelvanBiezen]

Great 👍

[@TheNikaProduction]

Amazing channel sir. Thank you

[@faicornelius2601]

I have an engineering question that is so challenging to me. How can post it to you for help?

[@MichelvanBiezen]

Our schedule is completely packed. We try to respond to questions when they are posted here.

Hi, how do I find the potential energy of a circular moving object (in cone)

[@MichelvanBiezen]

PE = mgh (the weight of the object x height of the object)

[@tttc3002]

why the centripetal force of bottom not pointing to the Center of the circle?

[@MichelvanBiezen]

That is not the centripetal force (which points to the center of the circle), but it is the fictitious "CENTRIFUGAL" force which points away from the center of the circle.

[@alfinuralbab114]

How if the position of thing is in 90 degree from bottom?

[@rna6760]

sir I understood the process but since this is a uniform circular motion, is not the magnitude of v supposed to be same for both top and bottom ?

[@akashhera]

Angular velocity is the uniform one, not the translational velocity

[@tuna34joseph]

Sır ıs not velocity constant in circular motion?

[@MichelvanBiezen]

Velocity is a vector quantity and thus has both magnitude and direction. The magnitude is constant but not the direction.

[@tuna34joseph]

ı know ı know . but in this example the magnitude of velocity on the top and bottom are not equal. Why?

[@jimmiriarty5799]

This question made me confuse conceptually.

[@theoendre6484]

velocity is constant (in magnitude) in uniform circular motion. In this example, the motion is not uniform due to the acceleration of gravity, hence the difference in the velocities.

Great
