Earth moment of inertia
WebAn example is the calculation of the rotational kinetic energy of the Earth. As the Earth has a sidereal rotation period of 23.93 hours, it has an angular velocity of 7.29 × 10 −5 rad·s −1. The Earth has a moment of inertia, I = 8.04 × 10 37 kg·m 2. Therefore, it has a rotational kinetic energy of 2.14 × 10 29 J. WebNov 1, 2024 · The moment of inertia from part A of the question (obtained online) is that of the Earth approximated to a perfect sphere. Mass of the Earth, M = 5.97 × 10²⁴ kg. Radius of the Earth, R = 6.38 × 10⁶ m. The rotational period of the Earth, T = 24.0 hrs

WebThe moment of inertia, otherwise known as the mass moment of inertia, angular mass, second moment of mass, or most accurately, rotational inertia, of a rigid body is a quantity that determines the torque needed … 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 …
WebRotational inertia is a property of any object which can be rotated. It is a scalar value which tells us how difficult it is to change the rotational velocity of the object around a given rotational axis. Rotational inertia plays a … WebThat means the Earth’s angular momentum must have decreased by 2.68x10 26 Kg. m 2 /sec during that same period. Since the change in the Earth’s angular velocity was -1.68x10-12 radians/sec during that time period, the Earth’s moment of …
