Question

It is seen that a falling apple is attracted towards the earth. Does the apple attract the earth? If so, we do not see the earth moving towards an apple. Why?

Answer 1

According to the laws of physics, the Earth attracts the apple and the apple attracts the Earth with the same intensity of gravity (3 law of Dynamics or Principle of Action and Reaction). However, the displacement of the two bodies (apple and earth) is inversely to the respective masses. Example: The Earth attracts the apple that falls 3 metres from a tree to the ground and the apple mass is very small compared to Earth. At the same time, the apple also attracts the Earth with the same force, but the Earth's mass is immensely greater than the apple's mass. So the Earth falls on the apple of a billionth of a billionth of a millimeter (or even less). Restart the fall of the Earth on the apple you will never be able to see.
