Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What two factors does the strength of gravity force depend on?
A
gravity and inertia
B
magnetism and friction
C
mass and distance
D
acceleration and mass
Explanation: 

Detailed explanation-1: -When dealing with the force of gravity between two objects, there are only two things that are important – mass, and distance. The force of gravity depends directly upon the masses of the two objects, and inversely on the square of the distance between them.

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: -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-4: -Answer and Explanation: The two factors that influence the weight of an object due to gravitational pull are acceleration due to gravity of the planet and the mass of the object. On Earth, acceleration due to gravity (g) is equal to 9.8m/s/s. The mass of the object varies and is measured in kilograms (km).

Detailed explanation-5: -Acceleration due to gravity (g) depends on the mass of the planet, It depends on the distance between center of planet and object. It depends on the shape of the planet, and rotational parameters of the planet.
