Uniform Circular Motion Problems

Physics Ninja looks at 3 uniform circular motion problems. Problem 1 is the conical pendulum, problem 2 is mass connected by 2 strings and problem 3 is 2 masses connected by a string and one mass is moving in a circle. We look at free body diagrams and how to apply Newton's laws for these problems.

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

[@cappmasters7253]

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

[@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!

[@maszdauna2518]

This helped me a lot, thank you :)

[@tianboqu7469]

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

[@sonderman8079]

That was brilliant. Thanks

[@dhruvalwadhi]

Perfect timing! Thank-you so much!

[@fawlen_eynjuhl]

Thanks for this

[@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 KZbinr. I checked out some of your vids. Keep up the good work!

[@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.

[@angelfabian2202]

So helpful

[@stalerice9470]

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

[@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!

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

[@mtado4933]

You are a god

[@lisandrolisandro8100]

great video. do more videos like this

[@PhysicsNinja]

Thanks, will do!

[@savitarcaptispoba]

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

[@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

[@barkbarkbark198]

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

[@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)

[@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!

[@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

[@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

[@yasodha340]

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

[@ezio_g]

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.😮

People got lazy and decided to drop the little g.

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

[@savitarcaptispoba]

:D

[@user-qf1bj1ul9h]

Tx is not equal to Tsin

[@connorcsabai1903]

ur incorrect
