Another paper that suggests Tracker is applicable to physics education!


Nowadays, students’ exploration as well as students’ interaction in the application stage of learning cycle can be improved by directly model real-world objects based on Newton’s Law using Open Source Physics(OSP) computer-modeling tools. In a case of studying an object rolling down a ramp, a traditional experiment method commonly uses a ticker tape sliding through a ticker timer. However, some kinematics parameters such as the instantaneous acceleration and the instantaneous speed of object cannot be investigated directly. By using the Tracker video analysis method, all kinematics parameters of cylinders rolling down a ramp can be investigated by direct visual inspection. The result shows that (1) there are no relations of cylinders’ mass as well as cylinders’ radius towards their kinetics parameters. (2) Excluding acceleration data, the speed and position as function of time follow the theory. (3) The acceleration data are in the random order, but their trend-lines closely fit the theory with 0.15% error. (4) The decrease of acceleration implicitly occurs due to the air friction acting on the cylinder during rolling down. (5) The cylinder’s inertial moment constant has been obtained experimentally with 3.00% error. (6) The ramp angle linearly influences the cylinders’ acceleration with 2.36% error. This research implied that the program can be further applied to physics educational purposes.
