Mechanical energy is one of the topics of learning physics in high school that is related to concepts and mathematical equations. Modellus is a computer application designed to explore mathematical models based on functions that are represented in the form of animations, graphics, and tables that are useful for focusing learning activities on understanding student physics concepts. In this study describes computational modelling activities using Modellus software and carried out the Modellus quality testing phase as a medium of physics learning to improve understanding of students' concepts on the topic of mechanical energy. Based on the data obtained, Modellus is included in the "very good" category used in physics learning especially on the topic of mechanical energy and critical thinking skills students obtain an average score of 65,45 in the "good" category using Modellus. © Published under licence by IOP Publishing Ltd.
