W Ek2 Ek1. The kinetic energy of a moving object is equal to the work required to bring it from rest to that speed or the work the object can do while being brought to rest. Therefore the 3 equations we need are.
Kinetic Energy Formula Rotational.
Derivation of kinetic energy formula. Definition for kinetic energy based on its charge and the voltage E. Kinetic Energy KE ½ M V2 Here M is the mass of the point mass in Kg or rigid body and V is the velocity msec at which it is moving. KE05times mtimes v2 where KE is kinetic energy in joules m is mass in kilograms and v is velocity in meters per second.
