Abstract Title: Decomposition of forces on inclined planes
Abstract: Students often struggle to decompose a vector, especially when calculating the vector components of an object on an inclined plane. In this study, we designed a vector survey in the context of physics and implemented it in an undergraduate university. Our preliminary studies indicate the students' learning difficulties in vector decompositions on incline problems. The analysis of the students' responses shows that placing a vector at the position with geometric convenience instead of the center of mass can help them identify angles and calculate vector components more accurately. Based on our current study, we observe an improvement in performance, when students are provided with the formula of vector components along with the definition of the angle in the formula sheet.
