2.
Why does Newtonian gravitation conflict with special relativity?

Answer





































3.
According to Newton, gravitational force

acts instantaneously
repels one body from another
is greater when objects are further apart
requires that two objects be in contact with each other






































4.
According to Einstein, a gravitational field can bend the path of . . .

5.
Consider a driver who hits the brakes hard and feels jerked forward as a result.  According to Einstein, this driver is entitled to say that he was sitting still all along and that it's the road (and other drivers and buildings and . . .) that suddenly decelerated.  How, then, do we explain the fact that this driver felt thrust forward against his seatbelt?

Answer





































6.
According to general relativity, gravity is

a force
curved spacetime
present in all reference frames
instantaneous action at a distance






































7.
If you are in free-fall, you will still experience

gravity
tides







































8.
If free-falling objects move in straight lines according to general relativity, why is the Moon's orbit around Earth an ellipse rather than a straight line?

Answer





































9.
According to general relativity, spacetime is curved by the presence of

matter
energy
both matter and energy
neither matter nor energy






































10. According to the equivalence principle, the effects of gravity are indistinguishable from the effects of
