What Materials Work Best for a Miniature Golf Ball Roller Coaster Track?

Click For Summary
SUMMARY

The discussion focuses on constructing a miniature golf ball roller coaster track for a physics project, with specific dimensions of 1 meter by 0.8 meters and a height of 1.5 meters. The recommended materials for the track include stiff wire, such as that used in dart board spiders or welding rods, arranged in parallel rails spaced approximately two-thirds of a golf ball's diameter apart. Additionally, the design should incorporate support loops that can be brazed or soldered to ensure stability. The feasibility of having the golf ball travel for 20 seconds after a 10 cm jump is questioned, indicating that such a duration is unrealistic without significant elevation.

PREREQUISITES
  • Understanding of basic physics principles related to motion and gravity
  • Familiarity with materials such as stiff wire and welding rods
  • Basic skills in soldering or brazing for track assembly
  • Knowledge of roller coaster design concepts, particularly for small-scale models
NEXT STEPS
  • Research techniques for constructing parallel rail systems for roller coasters
  • Learn about the physics of motion to optimize the golf ball's travel distance
  • Explore different materials suitable for miniature roller coaster tracks
  • Investigate design principles used in pinball machines for effective ball movement
USEFUL FOR

This discussion is beneficial for high school students working on physics projects, educators teaching principles of motion, and hobbyists interested in model construction and roller coaster design.

I have to make a roller coaster for a physics project and the dimensions of the project can be no larger than the mase of 1 meter by .8 m and 1.5 m tall. A golf ball is the object that must travel on the track and it must go through a loop and go off a 10 cm jump and travel for 20 seconds. My question is... What would be a good item to use for the tracks? I didn't know if there is a type of wood I could use or a type of putty/clay. Any good tips? thanks

If anyone wants to look at the project sheet I can attach that.

Welcome to PF, Mr. Hammer.
There seem to be a lot of roller-coaster projects popping up this year, and all are a bit different. I have no idea of what age or skill level you're at, so I'm going to assume for simplicity that you're early to mid high-school. That would imply a reasonably advanced tool-use level. My personal preference for a golf-ball track would be a couple of parallel rails spaced about 2/3's of a ball diameter apart (sorry, but I don't know exactly how big a golf ball is). I would use stiff wire, such as the 'spider' on a dart board is made of or maybe welding rod, with support loops brazed or soldered to the underside. If that's too vague an explanation, try looking at some pinball machines with wire ball return chutes to get a better idea.
I certainly hope you don't mean that the ball has to travel for 20 seconds during the jump from 10cm ramp, because that ain't going to happen unless your 10cm ramp is on the edge of a 50m cliff. :rolleyes:
