I do know that but It wouldn't have helped answer the question. It was just for the purpose of explaining that you could be traveling at a high speed and experience no change in weight. yes there is radial acceleration but it's small compared to the acceleration of gravity. Otherwise we would...

I am thinking that without drag that the passengers would feel complete weightlessness. When drag becomes a factor the plane will reach terminal velocity. Inside the plane while it is falling with constant terminal velocity the passengers would experience normal weight and gravity. Just like we...

I guess you could think of it in a way that states that a particle wants to return to its natural configuration with all field lines point straight outward/innward. So it seeks that natural state by moving. That definitely isn't an official law or anything but it definitely gets the idea across...

I am a little confused as to why my book is saying that the potential energy of a dipole is 0 at 90 degrees relative to the electric field lines. When it has the stored energy to turn from 90deg to 0deg if no force is acting on it. Wouldn't it make sense to use 0deg as a reference point then?
