Marble Funnel Physics

I ve come this far but i have no idea how to get it to hyperbolic shape.

Marble funnel physics.

The internal radius of the funnel at the top is 1 50 m. A marble of mass m is going around the funnel slowly making its way down to the bottom hole which is negligibly small. Common claim that the orbits of the rolling marble or coin are the same as the kepler orbits for planets revolving around the sun. Large marble funnel duration.

You need to find the time tau it will take for the marble to make its way down and the full magnitude of the final velocity on exit not only the. Im making 3d printed marble machine and i want to create a hyperbolic funnel like this. I ll be uploading plenty once i make some more. I know i should be using conic curve right.

Hey all long story short. As this marble goes around it experiences kinetic friction mu k only in the up down direction not the tangential direction. A 5 0 10 3 kg marble begins rolling a large circular orbit. These are my first marble runs all made out of a thick kind of.

It answers the question how do the coins spin around the funnel and not fall over and a whole lot more. At the bottom the funnel s neck narrows to an internal radius of 0 025 m. I m marblerunzfreak and im here to show you my unique and different marble runs. This section is all about the physics that interplay with the the spiral wishing well fund raising device and the vortx toy.

The set includes marble run stunt pieces such as a spinner slide marble jump double funnel and track splitter and much more. The entrance of a science museum features a funnel into which marbles are rolled one at a time. The marble run comprises a flexible plastic track built from two parallel rails much like a railway. Building and playing with the motorized elevator marble run is a great way to introduce children to the basic fundamentals of physics.

Other than the appearance it works 100 of the time. In fact it is straightforward to show that for no funnel surface can the kepler orbits be recovered. By adding measurement tools the mathematics underpinning the physics may be demonstrated in a very powerful way linking back to the original insights of mathematical scientists such as isaac newton. The marble run isn t that appealing considering the fact that there s duct tape all over it.

But theres so little documentation on it that im kind of l.
