This study aims to produce an e-module assisted by a professional flip PDF application based on guided inquiry on Newton's law material that is valid for students to use. The subject used is in class X at Gajah Mada 3 Palembang High School in the even semester of the 2020/2021 academic year. This research is a Research and Development (R&D) study using the ADDIE model which consists of 5 stages, namely Analysis, Design, Development, Implementation, and Evaluation. This research is only limited to the development stage due to time constraints and also the purpose of this research is only limited to developing and producing e-modules that are valid and practical. After conducting the research, the overall results were obtained, namely for validity based on material aspects, an average value of 88.8% was obtained in the "valid" category, and for the media aspect it was 90.85% "very valid". At the one-to-one trial stage, the average practicality score was 85.8% and the average test result was 81.7. At the small group trial stage, the average practicality value was 85.8% and the average test result was 80.Keywords: E-module, Guided inquiry model, Professional flip PDFDOI: http://dx.doi.org/10.23960/jpf.v11.n1.202301
