According to special relativity, this quantity equals mass times the Lorentz factor times the speed 
According to special relativity, this quantity equals mass times the Lorentz factor times the speed of light squared minus the rest energy. The temperature of a gas is proportional to the (*) average value of this for its particles. The change in this quantity is the work done on an object, and it is equal to one half times mass times velocity squared. As an object falls, its potential energy is converted into, for 10 points, what type of energy related to motion?
According to special relativity, this quantity equals mass times the Lorentz factor times the speed of light squared minus the rest energy.
