Main Question or Discussion Point
I was recently casually tosing a fork in my hand so it completed a 360 degree rotation with the handle landing back in my hand. I noticed that everytime I did this, the fork returned to my hand upside down (ie facing downwards). So it took a 720 degree rotation for it to come back in my hand the right way up. I tried this with spoons and my handphone and got a similar result. At first I thought the way in which I was tossing the fork might be causing it to rotate on a plane perpendcular to the plane of which I tossed the object. This may be the case; if not, I was hoping to understand the physical explanation of why an object spins in a perpendiclar plane to the direction of rotation, when it is tossed up. Thanks.
