Didn't we discuss this already? Yes, the point is that the horizontal momentum is conserved and the mass is the only thing with... -

Yes. If the radiation is isotropic in the frame of the emitter then it is not isotropic in the ground frame. In the ground frame the...

Indeed, in this situation, there is no acceleration of the emitter in either frame. We have an emitter with constant velocity and...

wnvl2 replied to the thread I Effect of Radiation Pressure on a Moving Object.Assume the radiation is uniform in the emitter's frame. In that case, there is no acceleration in that frame. However, from the...

If the radiation is absorbed by the object, then its mass must increase. And, by conservation of momemtum, it must slow down.
