Definition of angular momentum
WebNote that the angular momentum does not depend upon p rad p rad. Since the gravitational force is only in the radial direction, it can change only p rad p rad and not p perp p perp; hence, the angular momentum must remain constant. Now consider Figure 13.21. A small triangular area Δ A Δ A is swept out in time Δ t Δ t. WebNov 22, 2024 · What is the angular momentum of the object in number 1 above if it is rotating at 200 rad/s? 3.
