Abstract The main purpose of this laboratory experiment is observe the motion of a projectile in flight and investigate how R, range of projectile, and h, maximum height reached by the projectile, vary with θ, the launch angle. The experiment involves a projectile landing at the same height from which it is launched. Students will also learn how to accurately use a launcher and projectile. Students measured the values of R and h. Based on this data, the value for initial velocity, V o , was calculated to be 292.56 cm/s. Using this value, students were able to calculate theoretical values for R and h to serve as a basis of comparison. Possible errors include gross error, systematic error, and random error. Discussion Diagram Equations The following equations will be used in this experiment: R = [ V o 2 sin2θ] / g where R= range of projectile, V o = initial velocity, θ= launch angle, and g= acceleration due to gravity, 9.81 m/s 2 . h = [ (V
