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.
The unit of Inertia is kg and the Moment of Inertia is kg*m^2.
