Scientists explain the physics of hula hooping

A study from New York University examines the physics and mathematics behind how a hula hoop can appear to defy gravity, suggesting that certain body types may be better suited for the activity. The research identifies hula hooping as a form of mechanical levitation, influenced by rolling points of contact and body shape. Mathematicians also noted potential applications for enhancing energy efficiency and robotic positioning. This is the first study to explain the physics and math of hula hooping.
