The document describes vertical motion in one direction. It discusses free fall motion characteristics such as constant downward acceleration due to gravity of 9.8 m/s2. It provides the key equations for calculating variables like velocity, height, and time in free fall situations. It then discusses the characteristics and equations for vertically launched projectile motion, where an object moves upward and downward, acted on by gravity. Key variables and equations are presented for calculating the motion in both the upward and downward components of projectile motion.
