    Mass Relativity
AI Thread Summary
As objects approach the speed of light, their relativistic mass increases, affecting how they are perceived by stationary observers. A stationary observer does not directly observe an increase in mass of a distant object; instead, they perceive changes in the object's energy and momentum. The concept of mass as a sensation is clarified through the understanding of relativistic effects, which are tied to the object's velocity relative to the observer. The discussion highlights that the term "relativistic mass" is less commonly used in modern physics, favoring invariant mass instead. Understanding these principles is crucial for grasping the implications of relativity in physics.

We know that the OBSERVED mass increases as the objects approach near to the speed of light. I was wondering that how does a stationary observer observe an increase in mass of an object which is traveling far away from it. I mean mass is a sensation, how it is observed by a stationary observer?

Thread 'The Physics of unloading sand from a barge'

I think it's easist first to watch a short vidio clip I find these videos very relaxing to watch .. I got to thinking is this being done in the most efficient way? The sand has to be suspended in the water to move it to the outlet ... The faster the water , the more turbulance and the sand stays suspended, so it seems to me the rule of thumb is the hose be aimed towards the outlet at all times .. Many times the workers hit the sand directly which will greatly reduce the water...

Thread 'Why can't Solar panels be hemispherical, or a curved strip type?'

comparing a flat solar panel of area 2π r² and a hemisphere of the same area, the hemispherical solar panel would only occupy the area π r² of while the flat panel would occupy an entire 2π r² of land. wouldn't the hemispherical version have the same area of panel exposed to the sun, occupy less land space and can therefore increase the number of panels one land can have fitted? this would increase the power output proportionally as well. when I searched it up I wasn't satisfied with...
