Abstract
This study aims to determine the results of the validation test of digital teaching materials made using Flipbooks and to see an increase in students' understanding of the concept of momentum and impulse material. This research is included in research and development (R&D). Three experts carried out validation to assess the product developed from content, presentation, language and graphics. Based on the results of the validity test of the content feasibility aspect, the results obtained in the very high category, the presentation aspect in the High category, the language aspect in the high category and the visual aspect in the very high category. Furthermore, students are given a pretest and posttest questions to understand the physics concept. The average score for the pretest was in a low category; for the posttest, the average score was high. Based on these results, the digital teaching materials using FlipBook are valid, included in the high category, and can improve students' understanding of concepts
