Here on Earth, the vertical acceleration of any projectile is -9.81ms-2. The minus sign shows that they accelerate downwards.
This is true for an object dropped from a height, however the question refers to a projectile, which implies an object that has been launched by a mechanism. It thus has both a horizontal and a changing vertical acceleration in addition to the constant downward gravitational acceleration.

Is the vertical motion of a projectile accelerated?
Yes, the projectile needs to be accelerated to overcome the acceleration of gravity.
What is the vertical acceleration of a projectile if the vertical component of its velocity vector is zero?
The vertical component of a projectile's velocity is irrelevant. It can be up, down, or zero, makes no difference. As long as projectile motion lasts ... gravity is the only force on the object and you're ignoring air resistance ... its acceleration is constant, and is equal to the acceleration of gravity: 9.8 meters per second2 pointing down.
How do the horizontal components of a projectile motion vary from the vertical components?
Horizontal . . . acceleration is zero, speed is constant Vertical . . . acceleration is 'G' downward, speed constantly increases downward
What is the acceleration of a projectile when its instantaneous vertical velocity is zero at the top of its trajectory?
Acceleration at the point of zero vertical velocity will be equivalent to gravitational acceleration on that body. On Earth, for example, this is around 9.8 meters per second per second (9.8m/s2).
How does gravity affect the 2 components of projectile motion?
-- Gravity causes the vertical component of projectile motion to vary according to the local acceleration of gravity. -- Gravity has no effect at all on the horizontal component of projectile motion.
Is the vertical motion of a projectile accelerated?
Yes, the projectile needs to be accelerated to overcome the acceleration of gravity.

Why does the vertical component of velocity for a projectile change with time where as the horizontal component of velocity doesn't?
Because gravity is acting on the vertical component, exerting a constant -9.8m/s2 worth of acceleration.
What quantities remain constant in projectile motion?
All that I can think of are: 1.) Gravity 2.) Wind 2.A) wind speed 2.B) direction of wind 3.) Angle of trajectory 4.) Initial speed of projectile 5.) Material through which projectile travels (as in density) 6.) Mass of projectile 7.) Spin 7.A) speed of spin 7.B) axis/axes spining occurs on 8.) Shape of projectile 9.) Temperature of medium projectile is in 10.) Size of projectile (as in height, width, and depth) 11.) Weighting of projectile 12.) Obsturctions to projectile's path In a vaccuum, though, these are the variables: 1.) Speed of object 2.) Obstructions in path 3.) Gravity
For an object to be in projectile motion and what force must be acting on it?
Gravity must be the only force acting on the object, to produce downwards vertical acceleration. There is no force acting in the horizontal direction because there is no acceleration.
If a projectile is shot in the air neglecting air resistance what is its vertical accelrration?
the vertical accelaration in case of a projectile is 'g'.
Is acceleration greater when the object is thrown vertically or horizontally?
Acceleration is dependent on the initial velocity of how fast the object is leaving the projectile. The vertical acceleration is greater when the object is falling than when the object reaches the peak in height. However, if the object is thrown horizontally and there is no parabola in its shape then there is not as great of an acceleration.
What is the combination of horizontal motion with constant velocity and vertical motion with constant acceleration?
That combination is called "projectile motion". In the absence of air resistance, its shape is always a parabola.
