According to Newton's law of gravitation, every particle of matter attracts every other particle. But bodies on the surface of earth never move towards each other on account of this force of attraction. Why?                                    

Answer:

                Because of their small masses, the gravitational attraction between two bodies is too small to produce any motion in them. But due to the large mass of the earth, the gravitational attraction between the bodies and earth is very large and so all bodies are attracted towards the centre of the earth.
