Rotational Inertia Formula In linear motion, Newton's second law of motion states that the acceleration of an object is directly proportional to the net force applied to it but inversely proportional to mass. It is expressed as {eq}a=\frac{\Sigma F}{m} {/eq}, where a is the acceleratio...

Rotational inertia (otherwise known as moment of inertia) is a number that represents how much mass a rotating object has and how it is distributed. Read Rotational Inertia | Definition, Formula & Examples Lesson Recommended for You Video: Rotational Inertia Video: Moment of Inertia of a ...
Rotational Inertia Formula What is the rotational inertia? Rotational inertia is a property of any object which can rotate along some axis. It is a scalar value and it tells us how difficult it is to change the rotational velocity of the object around some given rotational axis. Rotational ine...
The rotational moment of inertia of a body has a radius of gyration Rg, which is measured relative to the body center of mass. One must integrate over the volume, which contains the solute particle. The above expression of Eq. (214) can be factored, which isolates the radius of gyration...
