Flywheel
OverviewHistoryPhysicsDesignMaterialsApplicationsSee alsoFurther reading
A flywheel is a mechanical device that uses the conservation of angular momentum to store rotational energy, a form of kinetic energy proportional to the product of its moment of inertia and the square of its rotational speed. In particular, assuming the flywheel''s moment of inertia is constant (i.e., a flywheel with fixed mass and second moment of area revolving about some fixed axis) th…

10.6: Calculating Moments of Inertia
Figure 10.6.3: Calculation of the moment of inertia I for a uniform thin rod about an axis through the center of the rod. We define dm to be a small element of mass making up the rod. The moment of inertia integral is an integral over the mass distribution. However, we know how to integrate over space, not over mass.

Rotational inertia (article) | Khan Academy
Rotational inertia is a property of any object which can be rotated. It is a scalar value which tells us how difficult it is to change the rotational velocity of the object around a given rotational axis. Rotational inertia plays a similar role in rotational mechanics to mass in linear mechanics. Indeed, the rotational inertia of an object ...

Inertia
The Main Idea. Inertia is the tendency of matter to resist change in Velocity. It is an inherent property of matter; the inertia of an object is directly proportional to its Mass and can in fact be used to define mass.

Moment of inertia
The cylinders with higher moment of inertia roll down a slope with a smaller acceleration, as more of their potential energy needs to be converted into the rotational kinetic energy. If a mechanical system is constrained to move parallel to a fixed plane, then the rotation of a body in the system occurs around an axis k ^ {displaystyle mathbf {hat {k}} } parallel to …
