Hi Sir , in the timeline 16:40 timestamp , you interpreted the diameter as 0.8m not the radius , therefore the radius is 0.4m. When following the formula (linear acceleration = radius * angular acceleration) , you will attain an answer of 0.4m * 2rad/s^2 = 0.8m/s^2
In example 7, you used the diameter vice the radius (80 instead of 40)to calculate the linear acceleration. Easy fix; change text to radius of the wheel vice diameter.
@@stepbystepscience more complicated problems and new stuff if possible reagrding rotational motion. Actually I don't know much about it, but I'd love to learn more from your videos.
14:58 Hello sir, in this problem in order to solve W final I used the kinematic formula: Wf^2 = Wi^2 +2.a.θ But I found Final angular velocity as Wf = 16.16 rad/sec, where you think I did wrong?
Hello Sir you are incorrect in number 7. The linear acceleration shoul be 0.8m/s², you forgot to convert the cm to m the radius is 0.4 not 0.8, Thankyou for this lesson Sir you explain it very nicely❤️👌
@@stepbystepscience Heyyyyyyy Today i had my midterm exam from physics. Trust me, i was preparing hard and i was studying with your videos. I do not know much in physics and i have poor background. But i know that everything is possible and if you put into the work, then why not to try strive for success? So going back to my exam, i was studying with your videos and i really liked how u go over through questions cuz physics is better understood through questions and practices rather than just formulas. I just wanted to say that i just aced that exam. And what is more important, i had similar question to those you analysed in your other videos. So i remembered all the notes that you made and i am so grateful to you. I passed it easily😎Thank you from the bottom of my heart❤️❤️❤️❤️❤️❤️❤️❤️

Yes, you are right.

Yes, diameter was the given unit's name. Answer for b.) should be half of his answer.
Will we get more rotational motion videos?? I'm loving them!!
I hope so! Are you looking for something in particular?

16:38 in the seventh problem shouldn't the radius be 40/100 m since the diameter is given as 80cm
Yes, you are correct, the diameter is given as 80 cm so the radius should be 40 cm. Sorry for my mistake.

Yes, you are right. Thanks for letting me know.
Good and easily understanding.
Glad it was helpful!
thank you for this!
You're most welcome!
These all seem to have much more given information than what my textbook gives. My textbook almost never gives time.
Glad that you found this resource helpful. Thanks for your comment.
Thanks
Welcome
Thank you so much
You bet, thanks for watching!
THANK YOU SO MUCH!
You're most welcome!

Thank you
Welcome!
Isn’t the answer for num 8 letter b 40?
THANK YOUUUUUUUUUU SOOOOOO MUCHHHHH
You're so welcome!
