Gravity vs force main
WebMar 28, 2024 · Main Differences Between Gravitational Force and Gravity Gravitational Force is the force that exists between two things in space, while Gravity is the force exerted by the earth on an object that is close to it. Attractive or repulsive is the gravitational force, whereas Only Gravity is Attractive.
