QUESTION:
The sun pulls on the moon with a force that is more than twice the magnitude of the force with which the earth attracts the moon. Why, then, doesn’t the sun take the moon away from the earth?
ANSWER:Solution 9DQ Step 1 There are two main gravitational forces acting on the moon. One is from the sun and the other gravitational force is from earth. In order to balance the gravitational pull of earth, the moon is revolving around the earth. So, it is a kind of freefall with constant speed. So, the moon can maintain a definite orbit around the earth to avoid a fall towards the earth.
