Areal velocity equal to the magnitude of the cross product of vectors "AB" and "AC". This area can also be viewed as a vector with this magnitude, pointing in a direction perpendicular to the parallelogram; this vector is the cross product itself: Hence The areal velocity is this vector area divided by Δ"t" in the limit that Δ"t" becomes vanishingly small: But, formula_4 is the velocity vector formula_5 of the moving particle, so that On the other hand, the angular momentum of the particle is and hence the angular momentum equals 2"m" times the areal velocity. Conservation of areal velocity is a
This Is What Rock n' Roll Looks Like at number forty-four on the US "Billboard" Hot Dance Club Songs. A music video for "This Is What Rock n' Roll Looks Like", shot and directed by Sanaa Hamri, was released on March 27, 2011.
