Gravity is a force that every mass exerts on every other mass. When you jump up in the air, not only does the Earth
exert a gravitational force on you, but you also exert a gravitational force on the Earth. You, of course, fall back down to
the Earth. Which of the following explains why the Earth is not moving toward you when you jump up in the air?
A. Earth exerts a gravitational force on itself.
B. You don't weigh enough to affect Earth's surface.
C. Your mass is very small compared to Earth's mass.
D. Earth's fixed orbit around the Sun keeps it from moving
