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.

What is the relationship between density?
Gravity, because of the structures of gravity, gravity has no measure whereas density has units of mass..

Does gravity affect a person's height and why?
What is the SG of water?
The specific gravity (SG) of water is a dimensionless quantity that is defined as the ratio of the density of water to the density of a reference substance, typically water itself at 4°C, where it has its maximum density of approximately 1,000 kg/m³. Therefore, the specific gravity of water is 1.0. This means that water has the same density as itself, which serves as the baseline for comparing the densities of other substances.
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?

What features of a planet affect gravity?

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 altitude affect to specific gravity and density?
Yes, altitude can affect specific gravity and density due to variations in atmospheric pressure. As altitude increases, atmospheric pressure decreases, leading to a decrease in density and specific gravity of gases and substances. This is important to consider when measuring and calculating these properties at different elevations.
How do you calculate pressure underwater and what factors affect it?
Pressure underwater is calculated by multiplying the depth of the water by the density of the fluid and the acceleration due to gravity. The formula is pressure depth x density x gravity. Factors that affect pressure underwater include the depth of the water, the density of the fluid, and the acceleration due to gravity.
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.
What are the factors that affect on rate of specific gravity?
The factors that affect specific gravity include temperature, pressure, and the density of the substance being measured. Temperature changes can cause the volume of a substance to expand or contract, affecting its specific gravity. Pressure changes can also alter the density of a substance, impacting its specific gravity measurement.
How does temperature impact the reading of gravity?
Temperature can affect the reading of gravity because as temperature increases, the density of the liquid in the gravity measuring device changes, which can lead to variations in the gravity reading.
Does air pressure affect gravity?
Air pressure does not directly affect gravity. Gravity is a fundamental force that acts uniformly on all objects regardless of air pressure. However, changes in air pressure can influence the density of the air, which may indirectly affect the behavior of objects falling through the atmosphere due to air resistance.
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.
What is the relationship between density?
