When an object falls to the earth, the earth also moves up to meet it. Why the earth's motion is not noticeable?


Expert Answer

An object falls to the earth because of gravitational attraction force. As we know, the gravitational force is mutual, so the earth is also pulled towards the falling object. 

But the mass of the earth is so large as compared to the mass of the object, so for the same magnitude of force the acceleration produced in the earth is so less that its not even visible to our eyes. Whereas, the ma...
