Why does your phone (or any flat rectangular object, like a credit card) flip on both its x and y axis, when you flip it from just the bottom?
It's called The intermediate axis theorem. Rotating your phone with its axis perpendicular to its face takes the most energy to spin it, because the corners are far from the axis of rotation. Rotating your phone with its axis perpendicular to the narrow usb end takes the least energy to spin it, …
The Short Answer
It's called The intermediate axis theorem. Rotating your phone with its axis perpendicular to its face takes the most energy to spin it, because the corners are far from the axis of rotation. Rotating your phone with its axis perpendicular to the narrow usb end takes the least energy to spin it, because the corners are closer. Rotating your phone with the axis perpendicular to the button side is in-between them, so it takes a middle amount of energy. This makes it unstable, or semi-stable. So it wobbles as it rotates. _URL_0_
