La rapidez suele ser confundida con la velocidad. ¿Qué es la rapidez? Es una magnitud vectorial, es decir, tiene módulo, dirección y sentido. Magnitud que sólo representa el módulo (medida numérica) de la velocidad. Es el cambio de velocidad en la unidad de tiempo Cambio de posición

Adiver in midair has an angular velocity of 6.0 rad/s and a moment of inertia of 1.2 kg·m2. he then pulls is arms and legs into a tuck position and his angular velocity increases to 12 rad/s. the net external torque acting on the diver is zero. what is his moment of inertia in the tuck position?
