Tracker Balloon Propelled Model FAQ

What is the Tracker Balloon Propelled Model?

The Tracker Balloon Propelled Model is an interactive simulation that demonstrates the principles of dynamics using a balloon propelled object. It is designed for junior college physics students and utilizes the Tracker software, which is compatible with Windows, macOS, and Linux operating systems.

What is Tracker?

Tracker is a free video analysis and modeling tool used in physics education. It allows users to analyze the motion of objects in videos by tracking their position over time. This data can then be used to create models and simulations of the observed motion.

How does the Tracker Balloon Propelled Model work?

The model uses a video of a balloon-powered object moving across a surface. Students can upload this video into Tracker and then use the software's tools to track the object's position in each frame of the video. The collected data points are then used by Tracker to generate graphs and calculate physical quantities like velocity and acceleration.

What physics concepts can be explored with this model?

This model can be used to explore numerous physics concepts, including:

• Newton's Laws of Motion: Students can observe how the balloon's expelled air (action) creates a force that propels the object forward (reaction). Additionally, they can analyze how the object's mass and the force of the air expulsion affect its acceleration.
• Conservation of Energy: Students can examine the transformation of potential energy stored in the inflated balloon into kinetic energy of the moving object.
• Projectile Motion: If the balloon-powered object is launched at an angle, students can investigate the principles of projectile motion, including analyzing the trajectory, range, and maximum height.
• Air Resistance: Students can investigate the impact of air resistance on the object's motion by comparing the model's predictions to the actual motion observed in the video.

What are the benefits of using the Tracker Balloon Propelled Model?

Using this model offers several benefits:

• Visual Learning: The model provides a visual and interactive way for students to learn about physics concepts.
• Hands-on Experience: Students can actively engage with the model by analyzing real-world video data.
• Data Analysis Skills: Working with Tracker helps students develop valuable data analysis skills.
• Conceptual Understanding: By manipulating variables and observing the results in the model, students can gain a deeper understanding of the underlying physics concepts.

How can I access the Tracker Balloon Propelled Model?

The model is available on the Open Educational Resources / Open Source Physics @ Singapore website. You can find it under the Interactive Resources section, specifically within the Physics, 01 Foundations of Physics, and 01 Measurements categories.
