Moment of inertia demonstration with cylinder

[AndreiMikhailovich]

Moment of inertia - a scalar physical quantity, a measure of inertia of a body in a rotational motion around an axis, just as the body weight is a measure of its inertia in the progressive movement. Characterized by the distribution of mass in the body: the moment of inertia is equal to the sum of products of elementary mass by the square of their distance from the base set (point, line or plane).

@AndreiMikhailovich Isn't it technically a tensor quantity?

@AndreiMikhailovich we have a misunderstanding.(мы друг друга не поняли .) but thanks for the details.

The solid cylinder has a smaller moment of inertia but it moves faster.

what is Moment of Inertia?
