This research aims to produce WEPMA on feasible work and energy materials in terms of materials, media, and educator responses. The research method used is research and development (R&D), using the 4D model (Define, Design, Develop, and Disseminate). The product developed is a mobile phone-based physics learning media on business and energy material which consists of 6 main components: homepage, competency, material, simulation, quiz, and profile. The results showed that WEPMA could be used as a teaching medium in the physics subject of work and energy based on expert judgment with outstanding categories for media, materials, and educator responses.
