SOLAR SYSTEM

Detailed explanation-1: -Gravitational force-an attractive force that exists between all objects with mass; an object with mass attracts another object with mass; the magnitude of the force is directly proportional to the masses of the two objects and inversely proportional to the square of the distance between the two objects.

Detailed explanation-2: -The force of gravity depends on the mass of the objects and their distance apart.

Detailed explanation-3: -Newton’s universal law of gravitation The force is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers of mass. This is called an inverse-square law.

Detailed explanation-4: -The gravitational force of attraction between two masses is inversely proportional to the square of the distance between the masses.

Detailed explanation-5: -Sir Isaac Newton (1642–1727) discovered that a force is required to change the speed or direction of movement of an object. He also realized that the force called “gravity” must make an apple fall from a tree, or humans and animals live on the surface of our spinning planet without being flung off.
