Can a Toy Car Run on Only Potential Energy Over an Elliptical Path?

Click For Summary

Discussion Overview

The discussion revolves around the feasibility of a toy car that operates solely on potential energy, specifically along an elliptical path, with only an initial impulse provided. Participants explore various constraints and mechanisms that could enable such a design.

Discussion Character

  • Exploratory, Technical explanation, Conceptual clarification, Debate/contested

Main Points Raised

  • One participant suggests using various mechanisms such as springs, falling weights, flywheels, or rubber bands to harness potential energy for the car's movement.
  • Another participant questions the constraints of the "initial impulse" and inquires about the size of the car, hinting at the possibility of using an electric car as a comparison.
  • A different participant raises the issue of what constitutes "inputs," suggesting that a timed steering mechanism might be necessary if electronic signals or mechanical interference are considered inputs.
  • There is a suggestion that achieving an elliptical path could be challenging, with one participant proposing the idea of using different sized wheels to create a circular path instead.

Areas of Agreement / Disagreement

Participants express differing views on the constraints and mechanisms involved, indicating that multiple competing ideas and uncertainties remain regarding the feasibility of the proposed design.

Contextual Notes

Limitations include unclear definitions of "initial impulse" and "inputs," as well as the specific requirements for the path-following mechanism. The discussion does not resolve these uncertainties.

Hey guys...
Is it possible to make a car running on only potential energy stored in it,..well the path is supposed to be horizontal & only the initial impulse is allowed.Also the vehicle is supposed to follow a certain path without any inputs while cruising.The path is supposed to be around 50 feet long and elliptical.
Any suggestions are welcome

The power bit is easy. Just use a spring, a falling weight, a flywheel, a rubber band, or if you're feeling sneaky, a battery.

What are your constraints for the path following? You could use an electronic system, - either tracking or with the path pre-programmed, or just a mechanical guide. Let us know more about your task.
 
I'm not sure I understand that "initial impulse" constraint. Also, what size car are we talking about here? As brewnog implied, you could buy yourself a nice electric car and drive it 100 miles, but I suspect that wouldn't fit with the spirit of what you are trying to do...
 
Just in case the term 'inputs' includes electronic signals or mechanical interference such as a track, then you might have to work a timed steering mechanism into the design. You could get a circular path by using different sized wheels on each side, but elliptical would be pretty tough. :confused:
