newtonian mechanics - What is the proof that a force applied on a rigid body will cause it to rotate around its center of mass?


Say I have a rigid body in space. I've read that if I during some short time interval apply a force on the body at some point which is not in line with the center of mass, it would start rotating about an axis which is perpendicular to the force and which goes through the center of mass.


What is the proof of this?
