Rotational Power, Work, Energy, Torque & Moment of Inertia - Physics Problems

This physics video tutorial provides a basic introduction into rotational power, work and energy. Rotational Power is equal to the net torque multiplied by the moment of inertia of the system. Rotational work is torque multiplied by angular displacement. Rotational work is also equal to the change in rotational kinetic energy. This video contains plenty of examples and practice problems on rotational power, work and energy.

Who are you, who are you so wise in the ways of science?

[alirezaaliyan]

do you have any train or exam for your lesson?

[josephhollingsworth]

I don’t know who you are but I love you, had a test before this but I feel good now, THANK YOU

Where can I find a set of practice questions for rotational work, power, energy torque and inertia? Seeing it once or twice doesn't help me remember long but if I got through a few dozen questions, I will have it. Please do advise!

Can we use the constant angular acceleration equation in this problem to find the angular acceleration at 8:06? Since, the problem does not say anything about the constant angular acceleration.

I have a problem if anyone can help me... Is w (omega) a vector? Do I have to put the vector sembol on top of w (omega)? The reason I ask this is because my teacher did not care my solution just because I didn't put the vector sign to velocity... So for that reason do I have to put vector sign to omega too? Please help me I usually cannot see vector sign to any solution i have seen.. but they told me it is a vector so i am in a dilemma 😢

2am studying for test im gonna bomb lol
