Great Circles Model Feature Summary

Featured Modeling
Great Circles Model
The Ejs Great Circles model displays the frictionless motion of a particle that is constrained to follow the surface of a perfect sphere.  The sphere rotates underneath the particle, but since there is no friction, and the sphere is perfectly spherical, the motion of the particle is not influenced by the sphere.
