SOLAR SYSTEM

Detailed explanation-1: -When placed at equal distances apart, the greatest gravitational attraction will be between two skateboards.

Detailed explanation-2: -This force of gravitational attraction is directly dependent upon the masses of both objects and inversely proportional to the square of the distance that separates their centers. This means that as you move away from an object the gravitational force decreases.

Detailed explanation-3: -Objects that are closer together have a stronger force of gravity between them. For example, the moon is closer to Earth than it is to the more massive sun, so the force of gravity is greater between the moon and Earth than between the moon and the sun. That’s why the moon circles around Earth rather than the sun.

Detailed explanation-4: -Gravity is affected by the size of objects and the distance between objects. A measure of the amount of matter in an object is mass. An object with a greater mass falls faster than an object with a smaller mass. When the distance between two objects increases, the force of gravity decreases.

Detailed explanation-5: -The gravitational force of attraction between two bodies is directly proportional to the product of their masses. It is also inversely proportional to the square of the distance between them.

Detailed explanation-6: -Hence, if the distance between the bodies is doubled, the gravitational force of attraction becomes one-fourth.
