The initial velocty of a projectile is non-zero.
A projectile has an initial forward velocity.
It is a projectile falling with an acceleration equal to that of free fall. (an object falling in a vacuum at the earth's surface)
c is correct.
Such an object is said to be in "free fall".
An object is said to be in free fall if the only force that acts on it is gravity.

As soon as it is launched, a projectile is in free fall.
well if you think about it free fall is just an object that falls down with no force besides gravity pushing on it. and projectile is also something or an object that has no force acting on it besides gravity. so there pretty alike. that is how they compare.

Such an object is said to be in "free fall".
An object is in free fall when only gravity and air resistance (drag) are acting on it. In space, free fall excludes drag.
An object in free fall is one that has only the force of gravity acting upon it.
An object is said to be in free fall if the only force that acts on it is gravity.
