Angular Momentum Physics Practice Problems

This physics video tutorial provides a few examples and practice problems on angular momentum. It explains how to calculate the angular momentum and rotational inertia of a spinning disk in the first problem. In the second problem, it explains how to calculate the average torque acting on a rod using angular momentum. The third problem discusses how to calculate the torque acting on a rod as well as the final angular momentum and final angular speed of the rod after a certain time period has elapsed. In addition, it explains how to calculate the work done by the force on the rod using rotational torque as well as rotational kinetic energy. The last problem discusses how to calculate the final angular speed of a merry-go-round after a child jumps on it using conservation of angular momentum.

Everybody says it, but I just gots to say it again, you're a life saver, you make me like physics and math. Great Job

[superhero]

you really should change your channel to "The All Knowing"

[rafaelvecchione]

This man will single-handedly save my physics and math grades.

[wottage]

you are carrying my future engineering degree rn

[ltcronin]

Oof ya girl didn’t fail her physics test so I came back to

[bcrbes]

Thank you so much. I’ve been watching your videos to help me study for me test and you have been very helpful. THANK YOU

[steammonkey]

you are the biggest man on youtube, you are a world changer.

[Rkive]

Thank you so much i wish if i found this channel earlier .. but what to do at least hope i will pass my final today

[TheHarleytrike]

Extremely well done! Excellent examples which will significantly help me solve the angular momentum FlipItPhysics problems. Thank you!

[Troy_]

great job. check 07:10 Wf=288rad/s shld be 28.8rad/s. thus the work is 8640J. thanks brah

[Starsnmoons]

Could you start to post a file with the questions so we can work along with you easier? I follow a lot of your videos and that would make things so much easier. Thanks again!

[akg]

how will we find volume, pressure and energy prameters from torque force?

[Witness]

Good luck to every one their physics test

[finianholland]

Please do a video on how to do the calculus for these.

[vishalsathiaseelan]

Thank you very much for having this practice problems. Many physics teachers just teach concept but dont do questions. During exam many students will PANIC! Thanks to your video i wont !

[sonduaalmelkar]

I think we have to use parallel axis Theron to calculate the moment of inertia of child??.. Please clear my doubt

[andrewhting]

Dude, all your videos are lit AF, but PLEASE turn your volume up! It's really quiet compared all the rest of the videos on youtube. Usually, Id just crank the volume up, but sometimes I study on my laptop without an external speaker, and they only get so loud.

Also, thanks again for your wonderful videos

[akilanmc]

hi dude for problem number(2) you found net torque, not average torque which was 6.25 . if I am wrong help me out

[starkendeavours]

Oh, man... These are very basic questions bring some bouncer or HArder questions from past year

[steveying]

Really, Absolutely, Completely, so fxxking good explanation!!!
