WebFeb 28, 2011 · This article is about moment of inertia and its physical significance. According to newton's first law of motion the body continues to stay in the state of rest or in the state of motion. This property of inertia possessed by all the matter is the measures of mass in translatory motion. Similarly when a body is rotating or fixed about an axis. http://mechanicsmap.psu.edu/websites/A2_moment_intergrals/A2-6_mass_moment_of_interia/massmomentofinteria.html
