The moment of inertia is in half as she draws her arms closer to her torso. A double increase in angular velocity.
The shift that an object / particle experiences with regards to time is expressed vectorially as velocity. The meter / second (m/s) is the accepted unit of flow speed (also known as speed).
The vector quantity velocity (v), denoted by equation v = s/t, quantifies displacement (not change in position, s), over change in time (t). Velocity (or rate, ) is a scalar number, denoted by the formula r = d/t, that quantifies the average distance (d) so over change in time (t).
