This study attempted to construct a low-cost projectile apparatus that will be used to produce photographs showing the similarities of the horizontal and vertical components of projectile motion to the motion of a body moving at constant velocity and to an object that accelerates uniformly using multiple-flash photography. Several pictures showing the following motions were taken and analyzed: 1. projectile motion (special case) 2. free-fall and constant velocity motions combined 3. free-fall and projectile motions combined 4. constant-velocity and projectile motions combined 5. constant-velocity, free-fall and projectile motions combined. Results of the study showed that within the limits of the accuracy of the measurements made, the following theoretical principles governing projectile motion were confirmed: 1. That the horizontal component of projectile motion and the motion of a body moving at constant velocity are similar and, 2. That the vertical component of projectile motion and the motion of a freely-falling body are identical. The study also showed that accurate results can be obtained using an improvised apparatus.
