Short Answer Key

1. Tracker is a free video analysis and modeling tool used in physics to analyze the motion of objects.
2. Five examples of physics concepts that can be modeled using Tracker include: projectile motion, collisions, oscillations, circular motion, and free fall.
3. Tracker can be used on Windows, Mac OSX, and Linux operating systems including laptops and desktops.
4. Answers will vary but could include an example like: A problem that could be modeled with Tracker is determining the acceleration of a ball rolling down a ramp. Tracker could be used to track the position of the ball at different points in time, and then this data could be used to calculate the ball's acceleration.
5. The purpose of using a modeling program like Tracker is to help visualize and understand complex physical phenomena, to analyze experimental data, and to make predictions about the behavior of physical systems.
6. Tracker can help students understand physics concepts by allowing them to visualize and interact with physical phenomena in a way that is not possible with traditional methods.
7. Three benefits of using Tracker in a physics classroom include: increased student engagement, improved understanding of physics concepts, and the development of critical thinking skills.
8. To use Tracker to analyze the motion of an object, you first need to import a video of the object in motion. Then, you need to calibrate the video by setting the scale and origin of the coordinate system. Once the video is calibrated, you can track the motion of the object by clicking on it in each frame of the video. Tracker will then calculate the object's position, velocity, and acceleration.
9. Answers will vary, but some limitations of using Tracker for physics modeling include: the need for high-quality video footage, the potential for error in tracking objects, and the limitations of the software itself.
10. Tracker software can be downloaded from the Open Source Physics @ Singapore website.
