sesquipedal การใช้

• :: Yes, the amount of matter remains constant ( unless it is losing mass to accelerate ), and the mass as measured by an observer on the moving body will not change from its invariant mass ( rest mass ) whatever the speed, but the apparent mass as observed by a " stationary " observer will seem to increase according to that formula ( without the sesquipedal power ? ) The apparent increase can be thought of as an illusion caused by the distortion of space-time, especially when you remember that an observer on the " moving body " will observe a relativistic increase in the apparent mass of the observer " at rest " on the Earth ( and of the Earth itself ) ."
