why do we assume this??
most problems on rotational mechanics which we do we are not provided with the rotational axis ...like in case of a sphere which when given some initial translational speed and left finally starts rolling we assume that it rotates about the axis passing through the c.o.m and perpendicular to it's plane...is this just an intutive conclusion based on say experiments or is that a 'theoritical' proof for it
