<![CDATA[The purpose of this research was to produce a practical tool on the restitution coefficient material. This research was development research. The research instrument used was a questionnaire. The questionnaire was given to media experts, 11th graders of SMA Negeri 1 Pamona Selatan and physics subject teachers. The obtained product quality data were analyzed using descriptive analysis, from qualitative data into quantitative data, then processing the average quality score using the criteria for the ideal category assessment. The quality of the product based on: media experts was 3.22 categorized as "Good"; students' responses in the limited trial was 2.8 categorized as "Agree"; and the feasibility analysis by the teacher was 3.86 categorized as "Very Good". The results of the trial and questionnaire analysis showed that the practical device consisting of everyday-life materials analyzed by the tracker was feasible to use, with the restitution coefficient value obtained by billiard balls of 0.8, tennis balls of 0, 7, ping pong ball of 0,7, wooden ball of 0,4, shot put ball of 0,1, iron ball of 0,1, and plasticine ball of 0,1.]]>
