Any object that is projected or thrown and is affected solely by gravitational pull is considered a projectile.
It manifests a parabolic path which is a result of two motions combined namely: vertical and horizontal.
The vertical motion is a free fall motion while the horizontal is a uniform motion.
Human beings can be compared to a projectile.
God allow us to free fall meaning to choose what is right or what is wrong.
Our tendencies to rise or fall depends on the sins that we will commit (i.e. is synonymous to gravity).
However, despite the degree of our rise and fall God always provides us with straight horizontal movement (constant guidance) to lead us to the right Range of our path...
