The magnitude of the force of attraction depends on the mass of the objects and the distance between them. For example, the gravitational force between two persons is minuscule; however, the gravitational force between a person and the [[earth]] is quite significant. If the person gets in a spacecraft and flies halfway to the moon, the gravitational force between him and the earth will significantly decrease because they are farther apart. The force will never become zero no matter how far he goes from the earth; however, if he goes far enough away, it will be counterbalanced by other masses' gravitational force. | The magnitude of the force of attraction depends on the mass of the objects and the distance between them.
