Question

Earth attracts an apple but earth doesnt move towards apple, why?​

Answer 1

Earth and apple both attract each other with same force ( gravitational force) but the apple moves towards the earth whereas the earth doesn't because the mass of earth is so that the force is negligible on earth and hence the earth doesn't move , also mass of apple is very low as compared to earth so it get attracted.

Answer 2

bcoz earth has its own orbit..with which it is surrounding ...and it also have its gravitational force
