By considering the centre of rotation as the instantaneous point of contact, it is actually harder to visualize and do problems.Usually, where I study, we consider the axis of rotation as any line of symmetry and make necessary adjustments. This way, complications will be avoided.

The COG CAN be considered as an axis of rotation. What else could one possibly consider as an axis of rotation? The mathematics would be least complicated when the axis of rotation passes through COG and perpendicular to the plane of the surface of the coin.

I did not "study" it yet. I'm just aware of its basics principles and some applications! :)

Hey! I'm a 15 years old student studying in India. I love to solve problems in physics and hope to become an engineer if not a physicist someday! I am a little familiar with special relativity, quantum mechanics and astronomy.
