Question

when a free falling object moves toward earth due to pull of earth on it. does earth also move toward the object due to reaction.
Explain?​

Answer 1

Answer:

Earth does not move towards the object.

Explanation:

By the universal law of gravitation, two bodies attract each other with a force that is directly proportional to the product of their masses and inversely proportional to the distance between them. So, theoretically, a free-falling object also attracts the earth in the same way the earth does. But comparing to the mass of the earth, the mass of the free-falling object is negligible. Hence the acceleration produced by the earth towards the object is also negligible. So we can say the earth does not move toward the falling object.
