Identifikasi Pemahaman Konsep Usaha dan Energi Calon Guru Fisika

This study aims to reveal the students' conceptual understanding on the concept of work and energy. In this study focused on discussing the ability of students to understand the concept of kinetic energy. To achieve this goal, 5 reasoned multiple choice questions were used. The question is a standard test of basic physics lectures at UM. This research is a descriptive research. The study was conducted on 50 students in the "Physics Content and Its Pedagogic I" course. The results showed that only 13 (26%) students correctly answered the relationship of K(x) from the F(x) graph and 10 (20%) students who correctly answered the K ratio of the two objects driven by the same force and displacement. Students' difficulties when solve the questions are more likely to be caused by the habits of students using mathematical equations without understanding their physical meaning, in addition students also have weaknesses in mathematical operations.
