When considering pure rotation of a rigid body about some point , then can we always consider the body to be concentrated in its centre of mass and use all force related equation treating it like a point object situated at it center of mass.? Why? Can anyone prove mathematically because there are many things like moment of inertia ,for e.g, for which we cannot do that.(adsbygoogle = window.adsbygoogle || []).push({});
