From tennis topspin to falling cats: the hidden physics of rotation
In short: Why does a spinning top remain upright while a rolling wheel stays balanced? This talk explores the shared physical principles that govern everything from athletic maneuvers to satellites in orbit.
In this Royal Institution lecture, Cambridge University Reader in Engineering Dynamics and Vibration, Hugh Hunt, investigates the common threads linking various rotating phenomena. He examines how angular momentum and rotation influence diverse movements, such as the way a cat lands on its feet, the mechanics of a boomerang, and the stability of satellites in space.
The presentation connects everyday examples, like topspin in tennis, to complex engineering and natural movements, revealing the underlying dynamics of the spinning world.
