Question

If the moon attracts the earth, why does the earth not move towards the moon?

Answer

The earth does not move towards the moon because its mass is extremely large.

Reason:

  1. According to Newton's Second Law of Motion, acceleration is inversely proportional to mass (a = \frac{F}{m}).

  2. Since the mass of the earth is very large compared to the moon, the acceleration produced in the earth is negligible (almost zero) and cannot be noticed.
