# Circular orbits on a warped spandex fabric

@article{Middleton2014CircularOO, title={Circular orbits on a warped spandex fabric}, author={Chad A. Middleton and M. A. Langston}, journal={American Journal of Physics}, year={2014}, volume={82}, pages={287-294} }

We present a theoretical and experimental analysis of circular-like orbits made by a marble rolling on a warped spandex fabric. We show that the mass of the fabric interior to the orbital path influences the motion of the marble in a nontrivial way and can even dominate the orbital characteristics. We also compare a Kepler-like expression for such orbits to similar expressions for orbits about a spherically symmetric massive object in the presence of a constant vacuum energy, as described by…
