Application: The speed that something rotates, such as a satellite spinning in space, is impacted by it’s inertia. A bigger inertia has a smaller angular acceleration.

Witryna12 gru 2024 · The first American satellite, Explorer 1, was launched in January 1958. The satellite, which was long and slender, was spin-stabilized about its long axis, the one with the smallest moment of inertia. However, the satellite had flexible antennae which oscillated, dissipating energy and destabilising the rotation. WitrynaThe moment of inertia of any object about an axis through its CG can be expressed by the formula: I = Mk 2 where I = moment of inertia M = mass (slug) or other correct unit of mass k = length (radius of gyration) (ft) or any other unit of length The distance (k) is called the Radius of Gyration.
