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 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.
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!
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.😮
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!
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
