## moment of inertiaThe moment of inertia I of a body about any axis is the sum of
the products of the mass dm of each
element of the body and the square of r, its distance between the
axis. I = Σr^{ 2}dm. Finding this
distribution of mass is important when determining the force needed to make
the object rotate. See also angular
momentum. ## Related category• CLASSICAL MECHANICS | |||||
