By bringing part of the mass of her body closer to the axis she decreases her body's moment of inertia. Becauseangular momentum is the product ofmoment of inertia and angular velocity, if the angular momentumremains constant (is conserved), then the angular velocity (rotational speed)of the skater must increase.

momentum = mass or inertia × velocity
here momentum can be changed by changing mass or velocity but mass can be changed only if velocity is above light speed i.e. 3× 10 power 8 . So to change momentum mostly velocity is change
