Given information
To Determine: Whether the Earth moves when object free falls on it.
Step-by-step explanation
Step 1.
Lets find the acceleration of the Earth and the object assuming the mass of the freely falling object to be m = 1 kg.
If the mass of the Earth is M, then the acceleration of the Earth would be found using Newton's laws of motion.
Acceleration of free falling object will be mg= 9.8m/s2
From Newton’s third law of motion: Every action has an equal and opposite reaction. Force on the Earth is:
Since the Earth has a mass that is on the order of 
, then the acceleration of the Earth is on the order of 
This value is very very small and this tiny acceleration is undetectable. So Earth doesn’t move.
