How does mass and density affect gravity?

Answer 1

Weight and density are two separate characteristics.

Density is the mass of material in a volume of material (1 g/cm3)

Weight is the force with which a mass is pulled onto the surface of another body. On Earth (for all normal considerations) 1 g (mass) is pulled towards the Earth with a force of 1 g (weight)

A given volume of material will weigh more if the density of the material it is composed of is higher. That is, 1m3 of aluminum will weigh less than 1 m3 of steel.

Answer 2

Mass and density both have an impact on gravity. The gravitational force between two objects is directly proportional to their masses. In the case of density, objects with higher density tend to have more mass concentrated in a smaller area, thus creating a stronger gravitational field around them.

Answer 3

Not at all. The force of gravity between two objects depends only on their masses

and the distance between their centers. Their volumes have no effect.

Another answer:

As for as one object goes:

Density of an object increases the escape velocity (or escape speed) which increases the gravitational force.

Answer 4

Density is expressed as mass per unit volume, Kg/m3. For a body at rest, we can consider its weight to be the same value its mass. Therefore, density is proportional to the weight of an object.

.

For example, two balls are both 5 cm (~2") in diameter. The first ball weighs 100g (~3 oz), and the second ball weighs 200g (~6 oz). The average density of the second ball is twice the average density of the first ball.

Answer 5

I guess that depends what quantities you choose to be variable, and what quantities constant.

mass = density x volume

weight = mass x gravity

Therefore, weight = density x volume x gravity

Thus, if you keep the volume constant (and gravity can be assumed to be constant), that would mean that if you have, for example, two object of the same shape and size (i.e., the same volume), the one with the greater density will also have the greater weight.

Answer 6

The amount of a substance does NOT affect density. Density is mass/volume and is an intrinsic property, meaning it is NOT dependent on the amount present. 1 gram of something has the same density as 100 g of that same substance.

Answer 7

Density is the mass of an object divided by its volume.

Answer 8

no because a Bowling ball is less dense than a glass marble, but they are different weight

Answer 9

Density is a function of mass and volume. So, density effects on the mass and the volume of the matter.

Answer 10

It does, because the amouunt of volume in a shape or anything does affect your denisuty.

EDIT: This answer is totally incorrect.
