Inertia and angular momentum
WebFind the angular momentum (L) of the Earth about its own axis: The angular momentum of the Earth about its own axis is given by: L = Iω. where I is the moment of inertia and ω is the angular velocity. Plugging in the values we found earlier, we get: L = Iω ≈ (9.822 × 10^37 kg m^2)(7.27 × 10^-5 rad/s) ≈ 7.07 × 10^33 kg m^2/s WebFigure 10.25 Calculation of the moment of inertia I for a uniform thin rod about an axis through the center of the rod.

Substituting for v, we get L = mr2w. But we also said L = Iw, where I is the rotational inertia. So for the case of the object of mass m at radius r, I = mr2.
Web1 mei 2024 · The angular momentum equation features three variables: L = angular momentum. / = the moment of inertia. W = the angular velocity. Note that angular … WebAngular momentum is a conserved quantity, which means that it stays constant providing no external torques act upon it, and is the product of moment of inertia multiplied by angular velocity. When the body has an increased radius, i.e. during the initial and final phase of a dive, moment of inertia is large and angular velocity is small.
