Angular Kinetic Energy, also called as Rotational energy, sometimes denoted by E ω is a measure of observed enery of rotating object due to its angular motion. It's often defined as the work needed to rotate a body or an object of mass from rest to its preferred angular velocity. Formula to calculate rotating body observed energy due to motion The rotational energy of a rolling cylinder varies from one half of the translational energy (if it is massive) to the same as the translational energy (if it is hollow). An example is the calculation of the rotational kinetic energy of the Earth. As the Earth has a period of about 23.93 hours, it has an angular velocity of 7.29×10 −5 rad/s By Boltzmann distribution formula one can calculate the relative population in different rotational energy states to the ground state. The relative population is governed by the energy difference from the ground state and the temperature of the system
