TED-Ed: The physics of the "hardest move" in ballet - Arleen Sugano

The video explores the physics behind the Black Swan's fouetté turns in ballet. It explains how dancers generate and maintain rotation through torque and momentum transfer, despite friction. The concept of conservation of angular momentum is key, as dancers adjust their rotational inertia by changing the position of their arms and legs to spin faster. The video highlights the intricate balance and skill required to perform these turns, emphasizing that while they may seem magical, they are grounded in physics.

What are fouettés and how do they relate to the dancer's ability to maintain rotation?

Explain the role of torque in the execution of a fouetté.

How does friction affect the momentum of a dancer performing fouettés?

What is the significance of the dancer's elevated leg during the fouetté?

Describe how a dancer can conserve angular momentum during a fouetté.
