Hi
have you any information for a teacher in Primary schools (children aged 6 - 11) to help explain Spinning Balls/Diabolos relation with gyroscopics? |

| | | Hi Steve,
I wonder does this help. If you tried to saw a billiard ball in half, rotating it into the saw blade as it cut, but the blade would not bit deep enough and so left a small center piece connection, you’d have a yoyo shaped like a ball and needing a string. Your ball-yoyo would in up and down oscillations spin, but otherwise spin as a gyro spins building angular momentum. Yoyos have some advantages that ship-stabilizing gyroscopes have. When the gyro attempts to tilt, the string and gravity attempt to straighten it up. As the attempt to straighten it begins, the gyro attempts to precess like a gyro in gimbals rings. As it attempts to precess (twist) it is caused to then attempt to twist and straighten vertically and so the end result is that the yoyo stays pretty much in its spin plain. The stabilizing factor is always angular momentum in either spinning ball or gyro. All spinning things from the big, the universe to the small, the quirk have the same spin quality, but you might say their qualities are somewhat varied in magnitude, yes?
This may be too elementary for you, but below is a wonderful part of this site that should help further.
