Marble Funnel Physics

Common claim that the orbits of the rolling marble or coin are the same as the kepler orbits for planets revolving around the sun.

Marble funnel physics.

Building and playing with the motorized elevator marble run is a great way to introduce children to the basic fundamentals of physics. I ve come this far but i have no idea how to get it to hyperbolic shape. A marble of mass m is going around the funnel slowly making its way down to the bottom hole which is negligibly small. 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.

These are my first marble runs all made out of a thick kind of. Build taller trickier marble runs with this deluxe set. At the bottom the funnel s neck narrows to an internal radius of 0 025 m. The internal radius of the funnel at the top is 1 50 m.

This section is all about the physics that interplay with the the spiral wishing well fund raising device and the vortx toy. But theres so little documentation on it that im kind of l. Large marble funnel duration. The marble run comprises a flexible plastic track built from two parallel rails much like a railway.

The marble run isn t that appealing considering the fact that there s duct tape all over it. I know i should be using conic curve right. Furthermore we find that the types of trajectories that can arise depend heavily on the funnel shape. 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. I m marblerunzfreak and im here to show you my unique and different marble runs. A 5 0 10 3 kg marble begins rolling a large circular orbit. As this marble goes around it experiences kinetic friction mu k only in the up down direction not the tangential direction.

It answers the question how do the coins spin around the funnel and not fall over and a whole lot more. 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 marbles circle around the wall of the funnel eventually spiraling down into the neck of the funnel.

Im making 3d printed marble machine and i want to create a hyperbolic funnel like this.
