Tracking Parabolic Trajectories with a Mobile Phone

Using a mobile device (mobile phone or tablet) as a recording system together with a free image analysis app, upper secondary and undergraduate students can experimentally obtain the equation of motion of a real system. In this study, the parabolic trajectories of spheres with diameters of a few centimeters were recorded and analyzed. The results of determining the trajectory were found to be quite close to the theoretical equations.
