The aim is to observe the time period of a sphere on a hemisphere with changing masses. It would be great if you could suggest any other ways to test the same. 20cm was chosen as the effect of damping on something smaller was significant leading to larger uncertainties.

I require balls (about the size of a small marble) of different masses. I have no idea how to go about this and your help would be greatly appreciated! I also need an hemisphere (about 20cm in radius). I though of 3D printing the same, and it's extremely expensive. Any alternative ideas...

My intended application for this is finding the top speed of a car around a particular curve governed by the equation above. The road would have friction with the tyres of the car. How would you suggest I find the radius at every point without doing so manually? Any mathematical techniques?

In general, for an object to stay in orbit (in this case continue in circular/elliptical motion), the outward force on the object must be equivalent to the centripetal force (I may be mistaken here) - in the case of an ellipse, there are two focii - which one would you pick in this case...

I understand that the centripetal force on an object of mass 'm' is (mv2)/r However, isn't this for an object going around in a circle? Suppose I have a curve (0.0033x2+−1.0038x+98.2331). What would be the fastest speed around this curve on the bounds x -> Please note that we would...
