Rotational Kinetic Energy, Moment of Inertia, & Torque

We define moment of inertia (rotational inertia), and use that quantity to derive formulas for kinetic energy and Newton's 2nd Law in rotational dynamics.

AP Physics C - Moment of Inertia

A brief introduction to moment of inertia (rotational inertia) for calculus-based physics students. For more information or help, check out http://APlusPhysics.com.

The Professor - Rotational Inertia and Gyroscopic Bicycle Wheels

Professor Julius Sumner Miller demonstrates the gyroscopic properties of a bicycle wheel.

Rotational Inertia - Effects on Horsepower

What effects does rotational inertia have on acceleration? Low moment of inertia components lead to more available horsepower. An explanation of rotational ...

“I want to feel weight and I want rotational inertia,” Shone says. “If you build them with plastic or something you buy at Guitar Center, you don't get that. I always liked the Les Paul custom guitar because it was the heaviest guitar you could get ...

This stubby outlet is in step with the current trend to greatly reduce a traditional long exhaust system's contribution to the machine's polar moment, or rotational inertia. The rest of the Stratosphere is up-to-date but basically conventional, and I ...

Magnetic couplings can typically only handle light torque loads and applications with either gradual starts, or low rotational inertia of the driven side of the system. They are also rather large in diameter, considering their relatively light torque load.

Just as more force is needed to accelerate a more massive object from rest, more rotational force – or torque, as physicists like to say – is needed to spin an object with more rotational inertia. You can increase this by carrying more mass, and by ...
