If the moon attracts the earth, why does the earth not move towards the moon
Answers
Answer:
Earth and moon is an example of two body system. They both rotate in an orbit such that the centripetal force required for circular motion is provided by the gravitational force. This is a very small value, and hence the centripetal acceleration is very small.

We know that,
The mass of earth is very huge as compared to the moon.
This is a very small value, and hence the centripetal acceleration is very small. Also, the mass of earth is very large and hence center of mass of earth and moon system is very close to earth. So, radius of rotation of earth is very small and negligible.
