It also enables us to find the electric field intensity at a place. The electrostatic force is important because it enables us to find the electric force experienced by a charge due to another charge (or charges). It is responsible for formation of tides in the oceans, etc.It is responsible for rotation of the moon around the earth.It is responsible for rotation of the earth around the sun.The following are facts that show the importance of gravitational force − The electrostatic force is stronger than gravitational force. The gravitational force is comparatively a weak force. If there are two bodies having masses M1 and M2 respectively and are separated by a distance of R meters, then the gravitational force is given by Therefore, for the existence of gravitational force between two bodies, the direct contact between the bodies is not required. Though, the gravitational force is a non-contact force. The gravitational force can be only an attraction force, it can never be repulsive. If out of two, one body is the earth, then it is called gravity. The force of attraction exerted by an object on another objects due to their mass is called the gravitational force. Before, going to discuss the differences, we learn the basics of gravitational force and electrostatic force so it becomes easy to understand the differences between them. Where, both gravitational and electrostatic forces are the types of noncontact forces. This article is meant for explaining the differences between gravitational force and electrostatic force. Where, 'F' is force, 'm' is the mass of body, and 'a' is acceleration (change in velocity of body due to force). Non-contact force is the one that acts on the body through space without having direct contact with the body.Ī generalized formula of force is given by the Newton's second law of motion, which is, Force may be classified into two broad categories namely contact force and non-contact force.Ĭontact force is the one that acts on a body by making a direct contact with the body. Thus, it has both magnitude and direction. Basically, a force is an external agent causes the change in the state of an object, i.e., it may move the object or may stop the movement of moving body.įorce is a vector quantity. Force is the factor that causes a change in the velocity of a body. Force is a physical quantity which is defined as a pull or push of a body having certain mass.
