Weba) The angular momentum of the Earth is given by: L = Iω where I is the moment of inertia of the Earth and ω is its angular velocity. For a uniform sphere, the moment of inertia is given by: I = (2/5)MR^2 where M is the mass of the Earth and R is its radius. WebThe moment of inertia of the Earth about its axis of rotation is 9.83 × 10 37 kg.m 2 and its angular speed is 7.27 × 10-5 rad/s. Calculate its (i) kinetic energy of rotation (ii) radius of gyration. [ Mass of the Earth = 6 × 10 24 kg] rotational dynamics; class-12; Share It On Facebook Twitter Email
WebThe moment of inertia is the quantitative measure of rotational inertia, just as in translational motion, and mass is the quantitative measure of linear inertia—that is, the … Web17 mrt. 2009 · The moment of inertia of the Earth depends on its rotation rate (angular velocity) because the equatorial bulge of the oceans depends on the angular velocity. If …
WebThe current rate of Earths angular deceleration is 1.4 ms/day/century which translates to about 3.73e-22 rad/s^2. Using these values solve the follow equation allows us to find a … WebOne of the principal moments of inertia of an ellipsoid of revolution is defined by the rotational axis. For an ellipsoid of revolution the remaining two of the principal axes of …
Web12 sep. 2024 · We defined the moment of inertia I of an object to be I = ∑ i mir2 i for all the point masses that make up the object. Because r is the distance to the axis of rotation from each piece of mass that makes up the object, the moment of inertia for any object depends on the chosen axis.
WebThe total moment of inertia is the sum of the moments of inertia of the mass elements in the body. Unlike mass, which is a constant for a given body, the moment of inertia … homes for sale in fienup in chesterfield moWeb17 sep. 2024 · Moments of inertia depend on both the shape, and the axis.
