The purpose of this study was to investigate high school students’ concepts about the motion of objects when considering the magnitude and the direction of the applied force. Students have a better understanding of uniform velocity than uniform acceleration, horizontal motion than vertical motion, straight-line motion than curvilinear motion, and the direction of a force than the magnitude of a force. In straight-line motion, the percentage of correct answers of the students was highest when the directions of the force and the motion were is the same and were in the horizontal direction. Also the orders of the percentages of correct answers were as following: vertical motion in the same direction, horizontal motion in the opposite direction, uniform velocity, and vertical motion of the opposite direction.
