A Learning Material for Physics Experiment with High-Accuracy Using Computer Vision Technique

Understanding a force causing the motion of an object is difficult for students who try to understand physics as scientific knowledge at first time, because of their empirical knowledge. To help their understanding of scientific knowledge, a data-taking and analysis system, with which they can carry on an experiment of physics easily, has been developed. The software records images including a moving object and extracts the trajectory of the object by using the computer vision techniques. With this system, the students can see the force vectors overlapped on the trajectory of the object. The accuracy of the force deduced from the images is discussed. physics, computer vision
