Derive the moments of inertia for a thin cylindrical shell or disc about its axis or an object that can be considered to be made up of coaxial shells (e.g., annular ring). INT-6.E

AP Physics C: Mechanics Practice Test 17: Rotation II: Inertia, Equilibrium, and Combined Rotation/Translation. This test contains 10 AP physics C-mechanics practice questions with detailed explanations, to be completed in 14 minutes.

This free AP Physics C unit 5 practice test on rotation consists of rotational analogs of linear quantities like angular displacement, angular velocity, and similar kinematical relations. Also, concepts of moment of inertia for discrete and continuous systems, rotational stability, and the law of conservation of angular momentum are considered.

Rotational inertia (also known as moment of inertia) is a measure of an object's resistance to changes in rotational motion. It depends on both the mass distribution within an object and how it is rotating about an axis. practice. cheatsheets scores videos

Post by Shehryar Khursheed on January 2, 2016. Hello Mr. Fullerton, I have a question about the moment of inertia of the cylinder. I noticed that you used an integral from 0 to R. However, I was wondering whether or not you can go the other way, and keep R constant while changing L; that is, going from the top to the bottom instead of inside out as you did.
