Why would you feel weightless if you were on a space-craft orbiting the earth?
A. Because the amount of gravity high up in space is almost zero.
B. Because you are a tiny object compared to the earth.
C. Because you are essentially falling around the earth instead of falling down into it.
D. Because gravity is proportional to the inverse-square of the distance, which means you are being attracted more strongly by the space-craft than by the far-away earth
