(the particle aspect of light) have no mass, they still carry momentum. Optical and Quantum Electronics. Therefore, dp1dtdp2dt, displaystyle frac dp_1dt-frac dp_2dt, with the negative sign indicating that the forces oppose. So, it depends on two factors that are how much and how fast an object is moved. 39 Consider a column of water in hydrostatic equilibrium. 32 :2 It has an electric potential ( r, t ) and magnetic vector potential A ( r, t ). A b c d Jackson 1975,. . Physics for Scientists and Engineers (6th.).

The calculation of the momentum of light within dielectric media is somewhat controversial (see AbrahamMinkowski controversy oxy Contin Addiction ). It's equal to mass multiplied by velocity. 61 See also edit References edit a b c Feynman Vol. The bodies have exchanged their velocities.
