Projectile Motion
When dealing with projectile motion physics students are normally allowed the assumption of two things;
1) The free-fall acceleration g is constant over the range of motion and is always directed downward.
2) The effect of air resistance is negligible, meaning there is no air resistance on the projectile.
With these assumptions we find that the projectile's path is always a parabola.

How this cheating pans out!
In theory this works out okay, but in the real world this is obviously not the case. When watching a soccer ball in flight it is easy to tell
that the ball has more than one force working on it besides it's mass and gravity. In other words, cheaters never prosper when it comes
to reality.
