## Does gravity depend upon density?

Specific gravity is in direct relationship with density. It is the ratio of an object’s density, and its contact substance. For example, if you want to place an object in water, the specific gravity would tell you if it would float or not.

## How does mass and density affect gravity?

Objects that are denser have a greater concentration of mass, thus creating a larger gravitational pull than a same-sized object with lower density—i.e., a cubic foot of solid rock will exert a larger pull on its surroundings than a cubic foot of ocean.

**Is gravity dependent on mass or weight?**

Weight is the vertical force exerted by a mass as a result of gravity. Weight can also be defined as the strength of the gravitational pull on the object; that is, how heavy it is. Weight is dependent on gravity.

### Does gravity only depend on mass?

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.

### Do you need gravity for density?

It is very useful when comparing the density of two objects. Since specific gravity is unitless, it doesn’t matter whether the density was measured in g/cm3 or in some other units (like lbs/ft3). You have a sample of basalt with density 210 lbs/ft3. The density of water is 62.4 lbs/ft3.

**What is the force of gravity on Neptune?**

11.15 m/s²

Neptune/Gravity

#### Is gravity an attractive force dependent on mass and density?

Basically, gravity is dependent on mass, where all things – from stars, planets, and galaxies to light and sub-atomic particles – are attracted to one another. Depending on the size, mass and density of the object, the gravitational force it exerts varies.

#### Is gravity proportional to mass or density?

So for Newton, the force of gravity acting between the earth and any other object is directly proportional to the mass of the earth, directly proportional to the mass of the object, and inversely proportional to the square of the distance that separates the centers of the earth and the object.

**Is weight dependent on mass?**

An object’s weight depends on its mass (the amount of matter it consists of) and the strength of the gravitational pull.

## What is mass dependent on?

Mass is a measure of how much force it will take to change that path. Mass depends on how much matter – atoms and so on – there is in an object; more mass means more inertia, as there is more to get moving. This force increases with the object’s mass: the more inertia it has, the harder gravity pulls.

## What is the density and gravity of water?

[density & sg of pure & tap water] [density/0.1°C] [coeff. expansion of water] [seawater] [steam] At 4°C pure water has a density (weight or mass) of about 1 g/cu.cm, 1 g/ml, 1 kg/litre, 1000 kg/cu.m, 1 tonne/cu.m or 62.4 lb/cu.ft. At 4°C pure water has a specific gravity of 1. ( Some reference the s.g.

**How is the force of gravity related to mass?**

Gravity is mass dependent. Gravitational force is directly proportional to the product of masses of the 2 objects attracting each other. Also acceleration due to gravity is proportional to the mass of the body. Mass can be converted into product of volume and density and can be equated in the Gravity equation.

### What is the mass of water at 4°C?

[seawater] [steam] At 4°C pure water has a density (weight or mass) of about 1 g/cu.cm, 1 g/ml, 1 kg/litre, 1000 kg/cu.m, 1 tonne/cu.m or 62.4 lb/cu.ft. At 4°C pure water has a specific gravity of 1. ( Some reference the s.g.

### How does the gravitational pull of two bodies depend on density?

The gravitational pull experienced by the two bodies, towards each other, will depend on the distance between their gravitational centres. If the diameter of the Sun reduces to, say, just 1 m (yes, one metre) with no change in its mass (implying a phenomenal increase in its density), its gravity will not change at all.
