Gravity
One of the four fundamental interactions, gravity is responsible for the fact that any objects with mass attract one another. According to general relativity, it is a space time curvature, but according to quantum mechanics it is the result of exchanges of virtual gravitons.

Which one is heavier 1kg iron or 1 kg cotton in vacuum?
The weight of a body in air is its apparent weight because the body body remains immersed in air . Therefore apparent weight of 1kg cotton and one kg iron is same .But volume of 1 kg cotton is greater than the volume of 1 iron
Do two objects dropped on earth land at the same time if they have different mass?
Yes. The only thing that can affect the speed of either object is air resistance. If there's none,
or if it's very small, then they fall with the same acceleration and land at the same time with
the same speed, no matter what their masses are.
A large amount of air resistnce with only a small increase in mass is introduced when a parachute is used. A parachute would be totally ineffective on the moon (no atmosphere, so no resistance)
What is tungsten's specific gravity?
Tungsten's specific gravity is around 19.25 grams per cubic centimeter, making it one of the heaviest naturally occurring elements.
Determination of specific gravity by you-tube?
There are two categories. One if the liquid is miscible with water then mercury is needed. If the liquid in not immiscible with water then no need to have mercury.
The simple idea is the pressure at the same horizontal level would be the same.
Pressure in turn is got by the formula hdg. Here h the height of the liquid above the some reference level. d the density of the liquid. and g the acceleration due to gravity.
If suppose hw is the height of water level and hl is the height of liquid and dw and dl are the respective densities of water and liquid, then specific gravity or relative density dl /dw = hw / hl (g getting cancelled on both sides)
Does gravity furnaces have filters?
No you need not adopt the unique furnaces, but that doesn't necessarily mean that you had best actually undergo with it once. Furnace Filters, Air Conditioning Filters at Air Sponge Filter Company
What particle is believed to mediate gravity?
The particle believed to mediate gravity is called a "graviton." It is a hypothetical elementary particle that is thought to be responsible for carrying the force of gravity in quantum gravity theories. However, gravitons have not yet been detected experimentally.
Factors that affect gravity between objects?
The force of gravity is
F=G*m1*m2/r^2
G is the universal gravitation constant 6.67*10^-11 m^3kg^-1s^-2
m1, m2 are the masses of the two objects,
r is the separation.
The force on m1 acts in the direction of m2, and the force on m2 acts in the direction of m1.
What is pull of gravity on an object called?
The pull of gravity on an object is called weight. Weight is the force exerted on an object due to gravity and is measured in units like pounds or kilograms.
Newton's law of Universal Gravitation states that:
F = G(m1*m2)/r2
where:
F is the force between the masses
G is the gravitational constant
m1 is the first mass
m2 is the second mass; and
r is the distance between the masses.
Is gravity the opposite of inertia?
No, gravity is not the opposite of inertia. Gravity is a force that pulls objects towards each other, while inertia is the tendency of an object to resist changes in its motion.
Balance refers to the equal distribution of weight or force in different parts of a system to maintain stability. In nature, balance is achieved through various mechanisms such as feedback loops, counteracting forces, or homeostasis. It is essential for maintaining harmonious relationships and preventing chaos or instability.
Gravity is not considered an external force because it is a fundamental force of nature that exists everywhere in the universe. It is always present and acts on all objects with mass, pulling them towards each other.
What is the value of specific gravity of portland pozzolana cement?
i am not satisfied with that specific gravity of portland pozzolana cement is 3.15
The object with the greatest force of gravity towards Earth at its surface will be an object with the largest mass, such as a mountain or a large boulder. Objects with greater mass will exert a stronger gravitational force towards Earth compared to smaller objects.
If two bodies of different mass fall from same height will they reach at the same time?
Yes - but only if you can ignore air resistance, that is, if the objects fall for a sufficiently short time, and have a sufficiently high mass, and sufficiently small surface area, so that air resistance becomes insignificant.

Does gravity have anything to do with math?
Without math, all you know is that things pull toward each other.
If you want to know any more details, you have to usemath.
That's kind of the same way math is involved with a lot of other subjects . . . .
Without math, you only know that putting more gas in the car costs more,
but you don't know how much.
Without math, you only know that driving faster gets you there sooner,
but you don't know how far, how fast, or how soon.
Without math, you only know that you have to mix a lot of things together to make a cake,
but you don't know how much of anything.
Without math, there aren't too many jobs you can do. You definitely can't be a scientist or an
engineer. You can't be a carpenter, because you can't measure anything or estimate lumber.
You can't paint houses, because you don't know how much paint or what size ladder you need,
and you can't tell the customer how long it'll take you to finish their house. And you can't drive
a taxi, because you can't count cash or make change.
Without math, you only know that you have to work longer to make more money,
but you have no idea how much for how long.
Without math, you only know that you can't pay for the house today,
but you don't know when or how.
Without math, you know that you need to mix some powder and some water to make the baby's formula.
But if you don't want her to starve, then you'd better get help from somebody who can do the math, because
you have no idea of how much.
Without math, chances are after a while you don't even know how old you are.
You don't know how to work it out, and there's no way to find out unless there's
someone still around who you can ask.
You can live without math ... if you want to call that 'living'.

42...actually its G=newtons gravitational constant =6.674*10^-11 m^3 kg^-1 s^-2 and is concerned with gravitational attraction calculations.
What is the specific Gravity of palmolein oil?
The specific gravity of palmolein oil typically ranges from 0.914 to 0.920 at 25°C. It may vary slightly depending on factors such as temperature and purity of the oil.
Gravity is primarily studied by physicists and astronomers. Physicists investigate the fundamental nature of gravity through theoretical frameworks such as Einstein's General Theory of Relativity, while astronomers study the effects of gravity on celestial objects and the structure of the universe.
Is acceleration due to gravity a scalar or vector?
Acceleration is always a vector, having both magnitude and direction, and the acceleration due to gravity is no exception.
Newton's law of gravitation gives the magnitude |F| of the instantaneous force vector F due to a particle of mass M on a particle of mass m as
|F| = GMm/r2,
where r is the separation and G is Newton's gravitational constant. The direction of the force is along the line connecting the two bodies, and it is attractive. By Newton's second law, m's acceleration vector g is given by
g = F/m,
which is in the same direction as the force and has magnitude |g| = GM/r2.
Note the following features of the above formulae. First, the force on M due to m is equal and opposite to the force on m due to M, as required by Newton's third law. Second, g is independent of m, i.e. all test particles in a gravitational field fall with the same acceleration, regardless of their masses, an observation of deep significance in General Relativity.
This statement is an example of inductive reasoning, where a general principle is inferred based on specific observations or experiences. The assumption is that because the law of gravity has held true in the past, it will continue to hold in the future.
