[Physics] Imagining to speed up the Earth’s revolution around the Sun until we feel its motion

centrifugal forceequivalence-principlenewtonian-gravitynewtonian-mechanicssolar system

If the Earth were revolving around the Sun much faster than it does, let's say 100 or 1000 times faster or whatever big-enough multiple of its actual speed, would we feel it? What sensation would we feel? How could I estimate how big the revolution speed would be for us to feel it? Would it be possible to speed up the Earth motion around the Sun? How? What basic physics concepts can be used to explain what would happen?

Best Answer

Well, it depends... If you just made the sun much heavier, so the earth would have to move faster in it's orbit, you wouldn't feel any different. It's just that the year would be shorter and the tides higher.

If you just put a rocket behind the earth and somehow put it on rails so it couldn't go to a different orbit, then you'd feel it. You'd be heavier in the daytime and lighter at night. If it was faster enough, you'd fly off into space at night, along with the air, the ocean, your room, a few new volcanoes, and everything else :)
