A satellite orbits the E0mu ,f6 imrha-arth along a gravitational equipotential liner07 mx7f67b(vhfhma)wnau3 gr k94s u. What shape must the orh 0rbkmrg 39f u f(7ahumavs467)wxn7bit be?
参考答案:
The orbit must be a
circle. The gravitational potential (or
potential energy) depends on the distance from the center of the Earth. If the potential is constant (equipotential
line), then the distance from the center of the Earth must be constant, and so
the orbit is a circle.
