If the balls were released at the very same time so that they meet exactly center of the non spinning disk, they would still collide on a spinning surface as they do when the disk is not spinning, correct?
The path the two balls take are aimed strait at the center, so they should still be on a collision course regardless of the motion of the disk if released at the same time, though they would not meet at the center as before. Thats my thinking anyway, was weird to not see the balls hit.
It's a potters wheel set a pretty much the lowest setting. The apparatus for launching the ball is just some pipe (pvc I think) clamped to the wheel. For the view from the rotating reference frame, a digital camera is duct taped to a stick, clamped to the wheel.
If you're in a crunch, find a playground with a merry-go-round.
Nice try but you guys have some major flaws in your aparatus. The forces acting on the balls on the spinning surface are NOT the coriolis effect per se. The spinning disc is imparting centrifugal force onto the balls. To be more accurate to depict the coriolis effect you need to attach the balls to strings and let them swing as pendelums over the spinning disc. That will show the "effect" without imparting a real force.
There are at least two clues that confirm indeed it is the Coriolis force being demonstrated and not simply friction between the disc and the ball. Anybody want to guess want to take a stab at it?
@OSUOC530 Right, because the friction is NOT enough to throw it off the straight path. The disc is moving underneath it, just like the earth is under eg. a bullet shot from S to N or N to S. It's just about POR
@OSUOC530 The balls change which direction they appear to angle due to the location on earth and the fact that the balls end at their projected point of exit as estimated by drawing a straight line from the entry point? Maybe? You said take a stab, I took more of a wild ass guess.
If it was friction, the balls wouldn't move in a straight line as is shown by the super imposed red line. If it was friction, the balls would curve counter-clockwise after reaching the center, but they continue to appear to be curving clockwise.
Friction is negligible since there is hardly any contact between a ball and a flat surface. Since the ball is moving, there's even less friction (easier to turn the wheel when the car is moving).
Like, this video is hosed because it's a 16:9 widescreen image horizontally squeezed (and distorted) into a standard 4:3 frame. Way to go, babes!

It's not a force that's for a sure.

well you didn't need to go to New Zealand to show the coriolis effect on that disc.

Hey guys
I'm making scientific project about this Coriolis Force and I'd like to know how to build that machine you used, and how to get the parts, etc
Please help me out!

Computer hard drives use wide beam lasers to compinsate for the coriolis effect during high RPM's.
