The gravitational force acting on a mass is the predominant factor determining projectile motion. The actual mass of the object is often irrelevant. To demonstrate this, an object of 100kg mass and an object of 1kg mass are simultaneously dropped from the same height, in vacuum. Observe, they simultaneously hit the floor. In an atmosphere, under conditions of similar geometry, objects of differing density will still fall at the same rate. A 3cm diameter sphere of lead, versus a 3cm diameter sphere of cork, they both have the same shape and size, hence the same aerodynamic properties. Observe, they simultaneously hit the floor. The masses were different, but they still hit the floor simultaneously.
When considerations of air resistance are taken into account, the density can certainly be a factor. (Remember, density is a ratio of mass and volume, or a description of how you use matter to create a structure of a given volume). To demonstrate this, a feather of 0.005kg mass and a solid lead ball of 0.005kg mass are simultaneously dropped from the same height. Observe, the lead ball heads straight to the floor, while the feather flutters about, landing quite a bit later. The air resistance acting against the feather is much greater, it's aerodynamic properties being much different than that of the sphere.
Perhaps not so much the density, but the aerodynamic properties, that affect projectile motion through a non-vacuum. Shoot a solid lead bullet through the air and see how far it goes. Then shoot a feather through the air - the aerodynamic drag forces acting on the feather act to slow it down - and see how far it goes.

∙ 15y agoNo, density is not affected by gravity. Density is the ratio of an object's mass to its volume. Neither mass or volume is affected by gravity, so gravity does not affect density.

What is the relationship between density?
Gravity, because of the structures of gravity, gravity has no measure whereas density has units of mass..
How does gravity affect a person's height or stature?
Does gravity affect a person's height and why?
How does gravity affect length of day?
It doesn't. For instance ... Earth & Venus have almost the same gravity yet Venus' day is about a year long Whereas Mars has but a quarter of Earth's gravity and its day is almost identical.
What is the density of rubber?
it depends type of rubber purity thickness length humidity also affect the answer
Difference between density and specific gravity?
Density is measured by mass per volume and the expressed formula is P=M/V where P represents Density, M represents Mass and V represents Volume. Specific density is a measurement of density relative to another substance and the expressed formula is Substance=P substance/ P reference. An example of specific density is measuring salt in ocean water and comparing it to salt in fresh water.
Is altitude affect to specific gravity and density?
no donot affect.
What features of a planet affect gravity?
mass and density
Does density affect gravity when mass is constant?
If the distance remains constant between the center of mass in question and an alternate center of mass, the density of either mass will not affect the gravitational force between the two centers of mass.
Is density the same thing as specific gravity?
Almost, but not quite. 'Specific gravity' is the density of a substancecompared to water.Numerically . . .Specific gravity of a substance = Density of the substance/Density of water.
What is the relative gravity on earth?
"Relative gravity" is used more or less as a synonym for density; it bears no direct relation with "gravity" as such. So, you would have to specify, "specific gravity [or density] of what substance"."Relative gravity" is used more or less as a synonym for density; it bears no direct relation with "gravity" as such.

Does gravity depend on density?
Gravity does not depend on density. Gravity is the gravitational pull that is invisible and cannot be touched or changed. Density is how much matter is packed within an object, which can be changed. Gravity and density are two totally different things, and are in no way related, therefore gravity does not depend on density.
How does volume affect specific gravity?
Specific gravity is otherwise known to be "Relative Density". It is the ratio of the density of a substance to that of water as water has been taken as standard. So though volume gets changed there is no chance to get change in the relative density as it is the characteristic property of the substance.

How does increasing attitude affect air pressure and density?
as the altitude increase, the effect of gravity become more insignificant on air and the air become more disperse or thinner hence it does affect the air pressure and density by decreasing both air pressure and density of the air.
What are three variables that don't affect gravity?
-- race -- creed -- color -- gender identification -- age -- political affiliation -- density
What are the factors that affect the bounce of a dropped ball?
size and weight of the ball, density of the ball matter, density of the surface , tilt of the surface, grade and finish of the surface, and of course gravity!
What is the differnce between density and specific gravity?
density is like weight and gravity is what pulls you to the ground density is what determines weight
