Kinetic energy calculator solving for velocity given energy and mass. The brief explanation is that this kinetic energy formula of ½mv 2 can be considered as an approximation of special relativity. Therefore the sum of the kinetic energy of a system of particles is the sum of all its constituent particles.
Kinetic energy is typically measured in units of Joules and 1 Joule is equal to 1 kilogram-meters squared per second squared.
Substitute the values in the below kinectic energy. 1 Tipler Paul A. When an object is in motion it is capable of doing work. M is the objects mass kg v is the objects speed ms.
