This study aims to determine the position each time y(t) of the modified ball (the ball is attached with a lump) and to analyze the impact of the distribution position of the lump attached to the ball. The ball is modified by adding variations number of bumps on the sides of the ball that are spread out in a tidy position. Variations number of lumps attached to the ball range from 2 to 10 lumps. Data retrieval is done by dropping an object in the form of a ball that is attached and recorded using a camera with a video quality of 250 fps. Each object variation is dropped with two different starting positions. First, the bumps are at the top and bottom of the ball. Then this position is called the "Vertical bump position". Hereinafter referred to as "Horizontal bump position" where this position is the first position to be rotated 900 so that the bumps are on the right and left of the ball. The recording results in the form of videos are then processed using Tracker Application to get the y(t) value. The results of the analysis show that the pattern formed on the graph of all objects is a quadratic function pattern. In addition, the initial position of the object being dropped greatly affects the speed of the object which then also affects the position of the object. The first position of the object where the bumps are located at the top and bottom makes the object move faster than the second position.
