Detailed explanation-1: -Gravitational force is an attraction between masses. The greater the size of the masses, the greater the size of the gravitational force (also called the gravity force). The gravitational force weakens rapidly with increasing distance between masses.
Detailed explanation-2: -A body that has mass always attracts another body having mass and the force between them is given by Newton’s law of gravitation. If there were repulsive gravitational forces, it would imply that the body has negative mass which is not possible. Hence, gravitational forces are always attractive in nature.
Detailed explanation-3: -Gravity is the force by which a planet or other body draws objects toward its center. The force of gravity keeps all of the planets in orbit around the sun.
