![]() The gravitational force is positive if that force keeps binding the two objects together and shows the force of attraction towards each other. It is a very tiny force of attraction between two objects comprising a mass. NEGATIVE G FORCE HOW TORead more on How To Find Gravitational Acceleration: Several Approaches and Problem Examples. The force reacting on each of the objects is equal but exerted in the opposite direction. “Every action has the equal and opposite reaction.” The gravitational force follows Newton’s Third Law of Motion, according to which, Gravitational Force of Attraction between Two Masses The gravitational force is always positive, but theoretically, we can write it as negative in vector form as the force of attraction between the two objects is exerted in two opposite directions.Ĭonsider two objects having mass M 1 and M 2 exerting a force F 1 on mass M 2 and force F 2 on mass M 1 respectively as shown in the below figure. ‘r’ is a shortest path joining the two objects The gravitational force is given by the formula F=Gm 1m 2/r 2 Read more on How to Calculate Mass from Gravitational Force: Several Approaches and Problem Examples. These objects can be easily pulled due to the gravitational attraction hence the negative gravitational force is in terms of the lighter objects also. If the mass of the object is less, then the gravitational force that it can exert on other objects is very less, or zero. The gravity of any object depends upon its mass. Hence, it is a theoretical explanation of the positive and negative gravitational pull of attraction. Here, it becomes difficult to say whether the gravitational force is positive or negative because mass can’t be a negative quantity. If we look into the electrostatics, based on the charges between which this force of attraction of repulsion comes into the picture, we can say whether the force is positive or negative. If the gravitational pull exerted by the body is minute then the distance of separation between the two objects will expand due to some circumstances or external forces then it is called a negative gravitational force. The gravitational force is an attractive force exerted between the two bodies having mass and that keeps them bonded together. Negative gravity is the antigravity between two objects that push them away from each other. The gravitational force is always positive, but since it is an attractive force between the two objects, it can be denoted by the negative sign. In this article, we shall discuss whether is gravitational force positive or negative and why gravitational force is denoted with a negative sign. ![]()
