Euler's+Disk

Euler's Disk

Euler's disk was a disk that was spun. When it was spun the Kinetic and Potential forces act together enabling it to spoll (spin and roll) for a long duration of time.

The Kinetic Energy is supplied by the mirror that the disk is being spun on. The Potential Energy is supplied by the angle at which the disk is spun at.

The disk would spin forever if it weren't for vibration and friction.

The disk is kept upright by angular momentum, as the disk is spinning round and round the circle it is held in place by gravity and the force of the mirror it is being spun on. Rounded edges to the disk maximise the duration of the spolling. As the disk is spinning it produces a whirring sound which is caused by the rapidly increasing motion of the disk.

Did you know that Euler's disk can spin for up to a 'WHOPPING' 3 minutes without stopping!!!!!! WOW!!!!! :+0
