GENERAL KNOWLEDGE

Detailed explanation-1: -Since gravitational force is inversely proportional to the square of the separation distance between the two interacting objects, more separation distance will result in weaker gravitational forces. So as two objects are separated from each other, the force of gravitational attraction between them also decreases.

Detailed explanation-2: -Earth’s gravity depends on the distance between the centre of the earth and the object on the surface of the earth. As the altitude increases, the distance from the centre of the earth increases. Therefore, the gravity decreases as it the inversely proportional to the distance.

Detailed explanation-3: -When the planet moves farther away, the speed and kinetic energy decrease, and the gravitational potential energy increases. At all points in the orbit, angular momentum and energy are conserved. This means that the Earth’s distance from Sun r varies throughout the orbit.
