When we compare horses with other animals, especially elephants, we come to know that the former have a much sharper and better memory than that of elephants. Horses have larger teeth and their size is not equal in males and females. A male horse has 40 teeth while a female has 36 teeth in total.
Moment of Inertia. The second moment, or moment of inertia, of a point mass m about the origin is the mass times the square of the distance to the origin, I = m(x 2 + y 2). The moment of inertia is related to the kinetic energy of rotation. A mass m moving at speed v has kinetic energy. KE = Â½ mv 2.
This article is about the mass moment of inertia of a rotating object. For area moment of inertia in beam bending, see Second moment of area. Tightrope walker Samuel Dixon using the long rod's moment of inertia for balance while crossing the Niagara River in 1890.
