This document discusses key formulas and concepts for projectile motion: 1) It provides the quadratic formulas for calculating the height of an object over time whether thrown or dropped, in both feet and meters. 2) It defines critical features of projectile motion formulas like the y-intercept, vertex, and roots which relate to the initial height, maximum height and time, and time it takes the object to hit the ground. 3) Examples are given of applying these concepts and formulas to the motion of a basketball to determine its initial height, maximum height and time, and time to reach the ground.
