GEOLOGY

Detailed explanation-1: -Both magnetism and gravity can affect objects at a distance. Both get weaker as the objects get farther apart. This is why you are affected by the pull of gravity from the earth, but not from distance planets.

Detailed explanation-2: -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-3: -Both gravitational and the magnetic forces are known as conservative forces. This property relates to work being path independent. That is, it takes the same amount of work to move a mass, in some external gravitational field, from one point to another regardless of the path taken between the two points.

Detailed explanation-4: -The force of gravity depends directly upon the masses of the two objects, and inversely on the square of the distance between them. This means that the force of gravity increases with mass, but decreases with increasing distance between objects.

Detailed explanation-5: -The size of the gravitational force is proportional to the masses of the objects and weakens as the distance between them increases.
