FAQ
What is VidMoLyze used for?
VidMoLyze is designed for physics and math classrooms to turn videos of motion into usable data. It helps students analyze concepts like free fall, projectile motion, and circular motion by extracting position, velocity, and acceleration data.
How does VidMoLyze help students learn physics?
It bridges the gap between theoretical concepts and real-world movement by allowing students to collect and analyze actual motion data from experiments. This hands-on approach can deepen understanding of mathematical principles behind physical phenomena.
What kind of data can I export from VidMoLyze?
You can export a clean CSV data file containing frame number, time, position (x and y), velocity (vx and vy), and acceleration (ax and ay) for each tracked point. This data is ready for use in applications like Excel, Google Sheets, or Python.
Is VidMoLyze suitable for a standard class period?
Yes, VidMoLyze is built to get students from raw video to usable data quickly, fitting within a typical 55-minute class period. It operates entirely on your device, eliminating the need for desktop software or complex setups.
Does VidMoLyze have ads?
VidMoLyze is free to use and is supported by a small, non-intrusive ad. Users can choose to support further development through donations.
What devices does VidMoLyze support?
VidMoLyze is currently supported on iPhones. It is rated for ages 4 and up.
How accurate is the motion tracking in VidMoLyze?
The app allows for precise manual tracking with zoom functionality for accuracy. Calibration using a known real-world measurement in the shot also helps ensure the reliability of the exported data.
Can I track complex motions with VidMoLyze?
VidMoLyze is capable of tracking various motions, including dropped balls, rolling carts, and pendulums. Its features are designed to analyze kinematics, projectile motion, free fall, circular motion, and terminal velocity.
