I think its because gravity is all around us. Materials are used to make structures and buildings, which will house valuable things. Which means the materials used will have to be able to take the gravity and the elements that are thrown at them.

as long as sun doesn't changes its gravitational force
The strength of the force of Gravity depends on the mass of the object exerting the gravitational force and the distance between the two objects. Gravity is the inverse of the square of the distance between the two objects, times the two masses. F = (G * m1 * m2)/(r squared) G is the universal gravitational constant G = 6.6726 x 10 -11 N-m 2 /kg 2
Your weight is the force that is exerted on you by gravity. Your weight is what pulls you down to earth, or indeed any planet or moon that you happen to be on.Your mass is simply a measure of how much matter there is. It is responsible for the force of gravity and so the greater the mass of either you or the celestial object that you're standing, then the gravitational force acting between you and the object will increase, and therefore so will your weight.Hence, as the local gravitational field strength is weaker on the moon compared to on earth (because of its lesser mass), on the moon your weight is also lesser, but your mass will remain the same.In everyday usage, measuring weight is a method of finding your mass. By measuring your weight, we can factor out the gravitational field strength, which is roughly constant across the planet, and find your mass. Thus we tend to talk about weighing ourselves, even though kilograms and stones are a measure of mass.
It means that the material has a low density. The practical implication is that a lot of it doesn't weigh much.
A tool called a gravimeter is used to measure gravity. Gravimeters detect variations in gravity strength by measuring the gravitational acceleration of the Earth at a particular location.
Planets have different fields of gravity because their mass and size vary. The larger and more massive a planet is, the stronger its gravitational pull will be. The strength of gravity on a planet is determined by its mass and radius.
No, temperature does not affect the force of gravity. Gravity is a fundamental force of nature that is determined by the mass and distance between objects, not by temperature. Temperature may affect the properties of objects or materials, but it does not influence the strength of gravity.
The strength of gravity of an object is proportional to its mass. The moon has much less mass than earth does.
Lift something against gravity and you're measuring its weight, which is the force acting on it due to gravity.
for the purpose of measuring the specific gravity
A gravimeter works by measuring changes in the acceleration due to gravity at different locations. This is typically done by measuring the displacement of a mass suspended in a spring system. By comparing the measured acceleration with a reference value, the instrument can determine variations in the local gravity field.
Shake something to and fro and you're measuring its resistance. Lift it against gravity and you're measuring its weight.
push= using ur weight against gravity/forcing weight agaisnt gravity pull=using strength to pull with/against gravity (sorry my answer isn't that great and scientific!)
Every speck of mass in the universe has 'gravity power'. The strength of the sun's gravity and the strength of the gravity of the lint in your shirt pocket can be calculated with exactly the same simple formula.
No mass is not affected by gravity, weight is.
It doesn't. Mass and distance affects the force of gravity.
