Escape velocity is the speed at which the kinetic energy plus the gravitational potential energy of an object is zero. It is the speed needed to
Potential energy is the energy of a body or a system with respect to the position of the body or the arrangement of the particles of the system. The amount
Compton scattering is an inelastic scattering of a photon by a free charged particle, usually an electron. It results in a decrease in energy (increase in
