Wind, elevation, trajectory, projectile weight, projectile configuration, barrel length, barrel rifling, friction or resistance in the barrel, force (charge) behind the projectile. There are other enviornental elements that can affect range as well.
In the typical projectile motion exercise at the middle school or
high school levels, where air resistance and the curvature of the
Earth are ignored, all you need in order to calculate the object's
time of flight is the upward component of its velocity (and maybe
the height from which it's launched, if that's significantly different
from the height at end-of-flight).
range = maximum value of your data set - minimum value of your data set.
The initial speed of the object, the angle at which it is fired at relative to the ground, the height it is fired from, and the acceleration due to gravity.
direct.
Individuals firing missiles will use Projectile Motion equations to determine where the missile will hit, so they can fire them with the correct trajectory at the intended target. An i-phone game, Angry Birds, uses projectile motion as well.
hypothesis on projectile motion
Because a projectile by definition, is in motion.
-- In what direction should a projectile be launched in order to achieve the maximum range ? -- Toward 45 degrees above the horizontal.
gravity
Projectile speed, projectile expansion, and projectile size are a few factors that determine intermediary range of a gun shot wound.

hypothesis on projectile motion
Because a projectile by definition, is in motion.
Projectile motion has two components horizontal motion and vertical motion. Gravity affects only the vertical motion of projectile motion.
-- In what direction should a projectile be launched in order to achieve the maximum range ? -- Toward 45 degrees above the horizontal.
45 degrees is the furthest one
Some of the factors that determine the movements of a projectile include: air resistance, force of gravity, initial launch velocity, the angle a projectile was launched at, and the objects initial elevation.

Gravity
A feather falling in a vacuum is not considered as a projectile motion. Gravity, which is absent in a vacuum, is one of the components of projectile motion.
