Detailed explanation-1: -The horizontal and vertical motions of a projectile are independent. Objects in projectile motion follow a parabolic path called a trajectory. If released at the same instant, a bullet shot from a gun will hit the ground at the same time as a bullet dropped from the same height.
Detailed explanation-2: -The x-direction and y-direction motions are independent in the sense that each of the one-dimensional motions occurs as if the other motion is not happening.
Detailed explanation-3: -There are the two components of the projectile’s motion-horizontal and vertical motion. And since perpendicular components of motion are independent of each other, these two components of motion can (and must) be discussed separately.
