What is projectile motion & ballistics?
Projectile motion combines independent horizontal and vertical kinematics. Without drag, horizontal velocity remains constant (vx = v0 cos θ) while vertical velocity decelerates under gravity (vy = v0 sin θ - gt), yielding a parabolic trajectory. With fluid drag, quadratic resistance F_d = ½ρCd A v² steepens the descent into an asymmetric tear-drop arc.
