Velocity the angular speed formula_27 and the magnitude of the displacement. such that Angular momentum in scalar form is the mass times the distance to the origin times the transverse velocity, or equivalently, the mass times the distance squared times the angular speed. The sign convention for angular momentum is the same as that for angular velocity. where The expression formula_33 is known as moment of inertia. If forces are in the radial direction only with an inverse square dependence, as in the case of a gravitational orbit, angular momentum is constant, and transverse speed is inversely proportional to the distance,
This Is What Rock n' Roll Looks Like been used by Lady Gaga. Ian Drew of "Us Weekly" called the single "shocking" and "electric". Allison Stewart of "The Washington Post" gave "This Is What Rock ‘n’ Roll Looks Like” a mixed review, describing Porcelain Black as a "girl-fronted version of Mötley Crüe circa Dr. Feelgood". Jon Wiederhorn of "Inked" dubbed the song "a euphoric digital feast of raspy melodic vocals, four-to-the-floor beats, and keyboards that buzz like electric guitars." "This Is What Rock n' Roll Looks Like" debuted on the U.S. "Billboard" Hot Dance Club Songs at number forty-six, on the week ending July 18, 2011. The following
