Vertical Contracted Drops
Description:
A flat surface is quickly removed from underneath the slinky, allowing it to drop vertically.
Problems: Friction between the surface and slinky causes the slinky to tilt horizontally as it falls.
Observations:
In all three clips, the slinky rotates from falling vertically to falling mostly horizontally after it leaves the flat surface. The slinky tilts in the same direction as that of the frictional force exerted on the slinky by the flat surface, as seen in the clips. It appears that regardless of how quickly the slinky is released, the flat surface unavoidably causes the slinky to rotate horizontally.
Other drop clips:
nvc1.avi--illustrates horizontal rotation well
nvc2.avi--flat surface slides out quickly from beneath the slinky, and the slinky still rotates horizontally
nvc3.avi (shown)--even an underhand release of the flat surface causes the slinky to rotate horizontally
