Why Is The Mass Of A Photon Zero? A massless particle Why do photons have zero mass? Photons have no REST mass, because they only exist travelling at the light velocity c. However, they do have a mass m (not a rest one !) given by the equation mc2 = h.nu, and there momentum is
What Is The Difference Between Mass And Rest Mass? The main difference between inertial mass and rest mass is that rest mass doesn’t change with the velocity of the particle with respect to the observer whereas inertial mass increases with the relative velocity of the particle with respect to the observer. What is rest mass
What Would Be The Momentum Of An Object If It Were Pushed To The Speed Of Light? At the speed of light, the object’s momentum would be infinite, so it would require an infinite impulse to get it there. When an object is pushed to relativistic speeds its momentum is? At relativistic speed, momentum increases
How Do You Calculate Rest Energy? Rest energy is E0 = mc2, meaning that mass is a form of energy. If energy is stored in an object, its mass increases. How do you calculate rest mass? One of the terms in the relativistic kinetic energy equation is the rest-mass of the particle and its given
What Are The 2 Types Of Mass? In classical mechanics, there are three types of mass or properties called mass: Inertial mass; passive gravitational mass; and active gravitational mass. What is the difference between gravitational and inertial mass? Gravitational mass is measured by comparing the force of gravity of an unknown mass to the force
