Answer Key

1. Tracker is a free video analysis and modeling tool used in physics to track the motion of objects in videos, analyze their movement, and create physics models.
2. Examples of physics concepts explored using Tracker: Projectile motion, conservation of energy, collisions, velocity, acceleration, forces, simple harmonic motion.
3. To analyze the motion of a toy car rolling down a slope, you would import a video of the car's motion into Tracker. You would then define a coordinate system and track the position of the car in each frame of the video. Tracker can then calculate the car's velocity, acceleration, and other relevant quantities.
4. Benefits of OERs like Tracker Car Rolling Down a Slope model include: free access, customizability, promoting collaboration, aligning with specific learning objectives, and providing engaging and interactive learning experiences.
5. Tracker can analyze a variety of video file formats, including .avi, .mov, and .mp4.
6. A teacher could use the "Tracker Car Rolling Down a Slope" model in a classroom by demonstrating it to students, having students conduct their own investigations using the model, or assigning it as homework to reinforce concepts related to motion.
7. Simulations and models are crucial in physics education as they offer visualizations of abstract concepts, allow for experimentation without physical limitations, facilitate exploration of "what-if" scenarios, and enhance student engagement and understanding.
8. The breadcrumbs navigation helps users understand their location within the website's hierarchy and easily navigate back to previous sections.
9. To explore projectile motion, you could use models like "Tracker Tennis Ball Model," "Tracker Projectile Modeling Motion," "Tracker Propulsion and Projectile Model."
10. You could record videos of a car rolling down slopes with different angles using Tracker. Analyze each video to determine the acceleration of the car on each slope. By comparing the acceleration values with the corresponding angles, you can investigate the relationship between them.
