The moment you push against it, it tends to resist and react or spring back with the same magnitude. According to Newton's first law, which characteristic of a moving object would remain constant if there were no other forces acting on it? since all objects are attracted toward each other because of gravity, why cant you see the objects moving toward each other. The two forces are equal. large objects have more mass, so more gravitational force. This allows us to define a pulling force as follows: A pulling force is a force in which an object moves towards the source of the interaction, either through direct contact or through the effect of a long-range force field.
