Chapter 1: Q9DQ (page 424)

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鈥檛 the sun take the moon away from the earth?

Short Answer

Expert verified

The centrifugal force due to the revolution of the moon around the sun is responsible for not letting the sun take away the moon.

Step by step solution

01

Significance of the gravitational force

The gravitational force is described as the attraction force between two or more bodies by virtue of their mass.

The concept of the gravitational force states the reason the sun does not take the moon away from the earth.

02

Determination of the reason for which the sun does not take the moon

The moon experiences two different gravitational attractions, one from the Earth and the other from Sun. As the moon revolves around the earth, the gravitational pull of the earth is nullified by centrifugal force. The moon revolves around the earth and the earth revolves around the sun, so the moon also revolves around the sun with the earth. Thus, the centrifugal force that is produced due to the revolution of the moon around the sun, nullifies the gravitational pull of the sun. hence, the moon is able to maintain its fixed orbit around the earth as well as around the sun.
