Law of Conservation of Angular Momentum
Law of conservation of angular momentum states the angular moment of a system of particles around a fixed point is conserved if there is no net external torque around that point.
law of conservation of angular momentum formulas
\(\large{ \Rightarrow\; \Delta L = 0 }\) |
\(\large{ \Rightarrow\; \Delta L_i = L_f }\) |
\(\large{ L = I \; \omega }\) |
Where:
Units | English | Metric |
\(\large{ L }\) = angular momentum (rotational momentum) | \(\large{\frac{lbm-ft^2}{sec}}\) | \(\large{\frac{kg-m^2}{s}}\) |
\(\large{ \omega }\) (Greek symbol omega) = angular velocity | \(\large{\frac{deg}{sec}}\) | \(\large{\frac{rad}{s}}\) |
\(\large{ L_f }\) = final angular momentum | \(\large{\frac{lbm-ft^2}{sec}}\) | \(\large{\frac{kg-m^2}{s}}\) |
\(\large{ L_i }\) = initial angular momentum | \(\large{\frac{lbm-ft^2}{sec}}\) | \(\large{\frac{kg-m^2}{s}}\) |
\(\large{ I }\) = moment of inertia | \(\large{ lbm-ft^2 }\) | \(\large{ kg-m^2 }\) |
