The HS Physics class has been working on vectors and projectile motion and we went out to the soccer field for a real life lab. The purpose of this lab was to study the properties of projectile motion. We first dropped the soft ball off the roof, to determine the vertical rate of falling and then launched with a water balloon slingshot on the soccer field. From the motion of a softball projected horizontally as well as at an angle, the initial velocity of the ball can be determined from the measured range. From this other properties of the motion can be determined. For a given initial velocity, the projectile range will be measured for various initial angles, and also calculated by applying the theory for motion with constant acceleration.
