, she reduces the distance between the axis of rotation and some of her mass, reducing her moment of inertia. Since angular momentum is conserved, her rotational velocity must increase to compensate. Let's estimate how much she speeds up by estimating the change in her rotational inertia.

The principle of the conservation of momentum is the law applied in the given figure. If the figure starts to spin with the arms spread wide, they have a large movement of inertia.

The skater starts off in a standing position and spins about the vertical axis. After few rotations , the skater pulls both arms closer to the body and spins fatser. In physics, we call it conservation of angular momentum.

conservation of momentum is used in the following figure she starts spinning with a vertical axis as soon as she starts spinning faster she pulls both arms to reduce friction

This is possible as an object's angular momentum will stay the same unless acted upon by an outside force.

Basically the ice draws her hands and legs in so as to reduce the distance between her axis of rotation and little bit of her mass. This reduces inertia. Then her angular momentum gets conserved her rotational velocity increases. Axis of rotation is the point around which a rigid body rotates. And inertia here is the rotating motion.
