Uniform Circular Motion Problems

[@alizo3]

one of the best channels on youtube about physics . Thank you Sir

[@PhysicsNinja]

Wow, thanks

[@scouterseth]

Bro. You are literally crazy good at explaining this stuff. Love the format and love the clarity.

[@Akshxt_307]

preparing for one of the toughest examinations in world (JEE ADVANCED) ,, and your lectures are really helping me bczz most of your videos are included in our syllabus

[@PhysicsNinja]

Good luck, you’ve got this

[@giannahandayan7900]

🤗🥺 I was already on the point of giving up on my physics classes until I found this channel. Thank you so much. This means a lot to us students.

[@PhysicsNinja]

You got this!

[@cappmasters7253]

You're the best teacher in the world ,thank u sir

[@tianboqu7469]

Finally found a video about the tension in centripetal motion! Thank you so much Physics Ninja!!!

[@user-nv1bo7dq2d]

thank you so much. this topic is really difficult for me but this helped a lot

[@thephysicschannelwithkenny314]

I enjoyed the video. I have not seen too many problems like the second one you did, but it was interesting. Most of the problem I have done on my videos are like the last one you did. Thanks.

[@PhysicsNinja]

Thanks Kenny. Nice to meet a fellow physics UA-camr. I checked out some of your vids. Keep up the good work!

[@sonderman8079]

That was brilliant. Thanks

[@derplerp8412]

This was the same thing on my physics midterm, thank you so much physics ninja!

[@PhysicsNinja]

Great news! I love hearing from viewers. I appreciate your comment, it motivates me to make more videos.

[@Ruby-bj8st]

The same exact problem was on my test! This video was a life saver. Thank you soooo much.

[@PhysicsNinja]

I love when that happens!

[@konradbrochocki4923]

In the first problem, could you also find the tension by using the negative of mg(since upwards is positive; g should be a negative acceleration) and then applying some trig since we already know our mass and angle of theta? I'm assume that the Ty component of the tension is just the opposite of mg.
Thanks. Great channel and video!

[@lisandrolisandro8100]

great video. do more videos like this

[@PhysicsNinja]

Thanks, will do!

[@dhruvalwadhi]

Perfect timing! Thank-you so much!

[@fawlen_eynjuhl]

Thanks for this

[@maszdauna2518]

This helped me a lot, thank you :)

[@user-pu3mj6cr5u]

why is Tx = Tsintheta and not Tcostheta ?

[@user-uc2pt9kq6u]

Same question here

[@MamosebetsiChaoane]

Because right angled triangleis formed and Tx is opposite to the theta
So when using SOH CAH TOA you will find that side as Tsintheta no Tcostheta

[@NomfundoMagudulela-lf1ck]

Yes that right.... the components depends on an angle

[@user-uf6nj3lz4v]

Tx equal to sintheta thats correct

[@MrWood-qd6kr]

Sin theta = centripetal force = x component

[@angelfabian2202]

So helpful

[@stalerice9470]

Thank you so much for this video! It was extremely helpful and saved me a lot of time.

[@savitarcaptispoba]

why can you just divide two equations like you showed on problem 1 and 2?

[@user-ts8rc7cn1r]

sry i can be wrong but i think that tx= t cos theta , ty= t son theta [ but you wrote the other way around] can you explain please. thank you

[@iamgingerbread6558]

is your velocity accurate in part 2, i keep getting 3.07 m/s

[@barkbarkbark198]

Why do people say tension is perpendicular to the bob in horizontal circular motion?

[@vrks1353]

Why would the answer for (ii) only take into account equation for m2 when there is also a force labeled T extending from m1? 24:41

[@Jimmy-de4sj]

Why didn't you use the length in the first problem to find Tx or Ty? Its the hypotenuse so why don't you just find ac that way?

[@rosalinechirishian5006]

i just dont get when the x component equals cos theta and when does it equal to sin theta. is there a fix rule?

[@astrofpv6656]

Build a triangle of your system and remember SOH CAH TOA (ie. sin=opp/hyp)

[@c4ipl02ankitsengupta9]

sir, can you please explain an application if the block under the surface is also rotating from problem 3 ???
please, explain sir.... my test is coming close

[@mtado4933]

You are a god

When people talk about how much they weight they talk about how much kilograms they weight but kilograms are units of mass and weight are in units of force, newtons, because weight is a force. So, why do we refer to weight in units of kilograms instead of using units of newtons. In orher words, If I am 95Kg I should say I weight 931 newtons instead of saying I weight 95Kg. My mass is 95Kg and I weight 931N. Therefore, a scale is a mass measuring device and not a weight scale. When I buy 1kg of tomatos, I'm actually buying 9.8 newtons of tomatos.😮

[@PhysicsNinja]

People got lazy and decided to drop the little g.

[@yasodha340]

In problem 2, why the tension value T2 is lesser than T1

[@doc_tray]

Hello, Physics Ninja. Thanks for this awesome video.
I understood everything explained in the video except for the last thing you mentioned about the mass m2 SPIRALLING DOWN.
Could you kindly elaborate on that? Why will that mass m2 spiral down if the velocity is less?
It would be of great help if you assist me with my question or refer me to another video or book for the explanation of my question.
Thanks!

[@kawsar929]

Hello there. I found a__c for question 1 to be -9.766679552 m/s^2 and not 0.944 m/s^2

[@twopoles11]

Check if your calculator is in degrees

[@user-qf1bj1ul9h]

Tx is not equal to Tsin

[@connorcsabai1903]

ur incorrect
