Projectiles (2D) A projectile is any object that is in a state of freefall, or in other words an object that is only acted upon by the force of gravity.

Goal: To projectile motions Objectives: 1)To understand freefall motions in 1 D 2)To understand freefall motions in 2D 3)To understand air drag and terminal.

Projectiles have two types of motion at the same time: Horizontal Vector An object travels at a constant speed (assuming no air resistance and no other.
