Astro Academy: Principia - Circular Motion

These resources include Tim’s on-orbit demonstrations of a ball on a tether and a ball in a circular track undergoing circular motion in various planes and the simple harmonic nature of displacement reduced to a single plane. Combined with the Earth based demonstrations of a cup of water travelling in a circle attached to a tether, and a loop the loop track, in-depth analysis of centripetal forces can take place.
