WebOne example of this principle in action is a gyroscope, which exploits the law of conservation of angular momentum to stabilize, guide or measure rotational movement in many types of systems. The law of conservation also explains why a spinning Frisbee soars on a stable trajectory through the air rather than dropping immediately to the ground ... WebAn example of conservation of angular momentum is seen in Figure 4, in which an ice skater is executing a spin. The net torque on her is very close to zero, because there is relatively little friction between her skates and the ice and because the friction is exerted very close to the pivot point.
