Tracker Fast Projectile Collision Model FAQ

What is the Tracker Fast Projectile Collision Model?

The Tracker Fast Projectile Collision Model is an interactive simulation created by Anushka Pisupati from Raffles Girls' School. It is hosted on the Open Educational Resources / Open Source Physics @ Singapore website. This simulation likely focuses on the physics concepts related to fast-moving projectiles and their collisions, allowing users to experiment and observe these principles in action.

What physics topics does the model cover?

The model primarily covers topics within Kinematics and Dynamics, which are fundamental branches of Physics. Kinematics deals with the motion of objects without considering the causes of motion (forces), while Dynamics studies the relationships between motion and forces. Specifically, this model may cover topics like:

• Projectile motion: The movement of an object projected into the air and subject only to gravity.
• Collisions: Interactions between two or more objects where they exert forces on each other for a short duration.
• Momentum and energy conservation: Principles governing how momentum and energy are transferred and conserved during collisions.

What is Tracker?

Tracker is a free and open-source video analysis and modeling tool. It allows users to analyze the motion of objects in videos by tracking their position, velocity, and acceleration over time. In the context of this model, Tracker is likely used to analyze video footage of a fast projectile collision. Users can mark the position of the projectile in each frame of the video, and Tracker will calculate its trajectory and other relevant parameters.
