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.

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

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

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.

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

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

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

@doc_tray 2 жыл бұрын

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!

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

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

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

@Jimmy-de4sj 3 ай бұрын

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?

@user-ts8rc7cn1r 2 ай бұрын

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 8 ай бұрын

why is Tx = Tsintheta and not Tcostheta ?

@user-uc2pt9kq6u 7 ай бұрын

Same question here

@MamosebetsiChaoane 6 ай бұрын

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 3 ай бұрын

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

@user-uf6nj3lz4v 2 ай бұрын

Tx equal to sintheta thats correct

Sin theta = centripetal force = x component

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.😮
