Short Answer Key

1. Tracker is a free and open-source video analysis and modeling tool used in physics education. It allows students to analyze the motion of objects in videos, create models, and compare experimental data with theoretical predictions.
2. Tracker can be used to analyze the motion of objects in real-world videos, such as a ball rolling down a ramp or a projectile launched into the air. It can also be used to create simulations of physical phenomena, such as the motion of planets in a solar system.
3. Tracker can track the position of an object moving in a circle over time. This data can be used to calculate the object's speed, acceleration, and centripetal force.
4. A "release (break) model" in Tracker refers to analyzing the motion of an object after it is released or breaks free from a constraint. For example, analyzing the trajectory of a ball after it leaves a spinning platform.
5. Tracker can plot the position of an object over time, allowing students to visualize how velocity changes. The slope of the position vs. time graph represents the object's velocity.
6. Three examples of simulations available are: Tracker Toy Car on High Acceleration Slope, Tracker Tennis Ball Model, and Tracker Projectile Modeling Motion.
7. Tracker is compatible with Windows, MacOSX, and Linux operating systems, including laptops and desktops.
8. Tracker encourages scientific thinking by allowing students to collect and analyze data, develop models, and test hypotheses, just like real scientists.
9. By tracking the trajectory of a projectile in a video, Tracker can be used to determine the object's initial velocity, launch angle, and range. Students can then compare this data to theoretical predictions based on the equations of motion.
10. Users mark the position of an object in each frame of a video. Tracker then uses this data to create a time-dependent dataset of the object's motion, which can be further analyzed and modeled.
