SOLAR SYSTEM

Detailed explanation-1: -The size of the gravitational force is proportional to the masses of the objects and weakens as the distance between them increases.

Detailed explanation-2: -A: As you move away from the Earth, the pull of Earth’s gravity weakens. Objects have mass and anything that has mass has gravity. The bigger the object, the stronger the force of gravity it exerts.

Detailed explanation-3: -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-4: -But, acceleration due to gravity (g) at distance ‘r’ from the centre of earth is given as, g = GM r GM r 2, therefore acceleration due to gravity (g) decreases with the increase in ‘r’. As a result, the value of gravitational acceleration (g) decreases as we go above the earth’s surface.

Detailed explanation-5: -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-6: -No. The mass of an object does never change no matter where it is in the universe.
