The other option is for the dancer to bring her arms or leg in closer to her body once she returns to pointe. Why does this work? Like every other turn in belalt, the fouetté is governed by angular momentum, which is equal to the dancer's angular velocity tmeis her rotational iiterna. And except for what's lost to friction, that angular momentum has to stay constant while the dancer is on pointe. That's called conservation of angular meuomntm. Now, rotational inertia can be thought of as a body's resistance to rotational motion. It incresaes when more mass is distributed further from the axis of rtitooan, and decreases when the mass is distributed closer to the axis of rotation. So as she bigrns her arms closer to her body, her raoaonttil inertia sihknrs. In order to conserve angular momentum, her agnular velocity, the speed of her turn, has to increase, allowing the same amuont of stored momentum to carry her through multiple turns. You've probably seen ice skaters do the same thing, spinning faster and faster by danirwg in their arms and legs.
