Moving electric charge induces magnetic field. Similarly moving mass should also induce some kind of field which is directly proportional to speed of mass. My guess is that moving mass induces opposite gravitational field which cancels out additional gravitational field generated by relativistic mass such that gravitational field of moving mass remains constant.
@@MichelvanBiezenYes. But, how do we account for relativistic kinetic energy. In KE & Momentum equations for mass bearing objects only mass & velocity appear. We can measure velocity so we know relativistic KE does not go into increasing the velocity. This leaves only mass, if mass does not increase then where does this energy go. In free space moving mass can only interacts with Space as there is nothing else around it. Therefore, this relativistic KE has to do something with Space. If moving mass does not induce opposite field, like back emf, or negative gravity then this energy must be carried and ultimately lost to Space. It is just like entire input energy does not into moving a boat, it is partially used in moving the boat & rest goes into overcoming the friction & carried by water waves. For this Space has to have a physical nature.
Sir, could make video on how did ampere developed his ampere force equation.... Without using Lorentz force equation.. Lorentz force equation developed by lorentz in 1895.. But Ampere developed his equation in 1825..Every video in you tube, tutors are driving ampere's law with help of lorentz force equation..
put 2 wires side by side 1 meter apart...put current thru both wires, both wires will be attracted to each other by a small force (u)....2 wires 1 light second long with 1 ampere will attract a force of 60 newtons!! around 15 pounds!!
