INTENSITY IS THE MOTHER OF ALL FORCES INCLUDING GRAVITY ! No MASS!!!

Form of Intensity of the Moving Charge Electric Field is Asymmetrical.
NO MASS!!

E(mov)= E(still)[1 - (v/c)cos(theta]^2

For the sake of simplicity let us consider for instance the gravitational field of the Earth. Analogically to (2.20), for the intensity of the gravitational field one could write

g(mov)= g(still)[1 - (v/c)cos(theta]^2


Subsequently valid:

Kinetic energy of a particle ( charge) moving at the velocity of v has two different values:

Kinetic energy of a particle ( charge)

Tkin id =mc^2 [ln |1-v/c|+ (v/c) / (1-v/c) ] in direction of motion of a particle ( charge)

It is realy as Newton´s kinetic energy,

where v is velocity of a particle ( charge) .

Kinetic energy of a particle ( charge) Tkin ad = mc^2 [ln |1+v/c|- (v/c) / (1+v/c) ] against direction of motion of a particle ( charge)

It is realy as Maxwell´s electromagnetic wave energy,

where v is velocity of a particle ( charge).

If the body of mass m moves in the transmission medium, then his own kinetic energy

equals Tkin id =mc^2 [ln |1-v/c|+ (v/c) / (1-v/c) ]

and the kinetic energy created by the body in transmission medium
equals Tkin ad = mc^2 [ln |1+v/c|- (v/c) / (1+v/c) ]
