Answer Key

1. Tracker is a free, open-source video analysis and modeling tool used in physics education to analyze the motion of objects in videos. It allows students to track the position, velocity, and acceleration of objects over time, create graphs and data tables, and model the motion using various physics principles.
2. The "Tracker Bird in Flight" simulation allows users to analyze the motion of a bird in flight by tracking its position in a video. It helps students understand concepts like projectile motion, air resistance, and the forces acting on objects in motion.
3. Tracker can collect data on the position (x, y coordinates) of an object in each frame of the video, enabling the calculation of displacement, velocity, and acceleration.
4. Tracker analyzes motion by allowing users to mark the position of the object in each frame. It then uses this data to calculate various kinematic quantities, generate graphs and data tables, and apply physics models to the motion.
5. Calibrating the video in Tracker involves defining a known distance in the video, which helps Tracker convert pixel measurements to real-world units. This ensures the accuracy of the data collected.
6. Challenges in using Tracker can include low-quality videos, difficulty in accurately tracking the object, and understanding the software's features and functionalities.
7. Tracker can model projectile motion by tracking the trajectory of a projectile and fitting the data to the equations of motion. It can also incorporate factors like air resistance and launch angle.
8. Setting a coordinate system in Tracker provides a reference point for all measurements, ensuring consistent analysis and allowing for the calculation of vector quantities like displacement and velocity.
9. Tracker helps students visualize concepts like velocity and acceleration by generating graphs that show the changes in these quantities over time. It also allows for the creation of motion diagrams that illustrate the object's path and velocity vectors.
10. Three physics concepts that can be explored using Tracker include: projectile motion, free fall, and collisions.
