Does Resistance Affect Projectiles?

As a projectile moves through the air it is slowed down by air resistance. Air resistance will decrease the horizontal component of a projectile. The effect of air resistance is very small, but needs to be considered if you want to increase the horizontal component of a projectile.

Why does air resistance do to a projectile?

During the motion of a projectile, however, air resistance continuously retards its motion. As a result, the deviation of the actual trajectory of the projectile from that calculated by neglecting air resistance increases as the launch speed, size of the ball, and the time of flight increases.
