Uniform Circular Motion Problems 

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

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

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

🤗🥺 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.

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

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

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.

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

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

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

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!

That was brilliant. Thanks

why is Tx = Tsintheta and not Tcostheta ?

great video. do more videos like this

This helped me a lot, thank you :)

Perfect timing! Thank-you so much!

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

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

Thanks for this

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?

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

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

So helpful

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.😮

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

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

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!

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

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

You are a god

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

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

Tx is not equal to Tsin
