Analysis of the falling patterns from height using Tracker program

Abstract

This research aims to analyze the horizontal distances (s_x) of falling by using Tracker program with
the theoretical examination of the projectile motion. The tested puppet was examined by the shooting of fall model with non-external force and with the external force of 4, 5, 6 and 7 bars from the 11 meters (s_y) height building. The research found that the horizontal distance where the average distances are 2.41, 2.47, 3.05, 2.59 and 2.48 meter, respectively. In addition, with the external force of 6 and 7 bars, the horizontal distances were found to be closer to the building due to the effect of a rotational motion as the center of mass was not forced. Consider the projectile motion under all conditions, the relationship between horizontal distance (s_x), velocity (v) and time (t) were found to be consistent with the theory. The velocity of the falling can be estimated by the proposed equation v_x= 0.70 s_x (s_y)^-1/2 + 0.30
