It is said in my textbook that to set a puck into both translational and rotational motion, we can simultaneously push the puck (with any linear velocity) and rotate it (with any angular velocity).
I don't think we can set an object into both translational and rotational motion with only 1 force. It requires 2 forces - one applied at the puck's center of mass, giving it linear motion; the other applied at any other points of the puck except for its cm, to set it into rotation around its cm.
However, when I tried out flicking a wite-out at its edge in real life, it not only rotates but also moves forward (ie has linear motion).
I am wondering why this happens, does it mean we only need one force to set an object into both translational and rotational motion theoretically as well?
