The labs in this unit use a video tracking app called “Video Physics”. Video Physics is available for both Apple and Android devices. Video Physics is a product of Vernier Physics. The current cost (as of 9/22/2015) is $4.99 but you may be able to put one app on multiple devices depending how the iCloud accounts are set up.
Video Physics allows a student to film an object in motion and place tracking dots on top of the object as it moves. If given a scale, Video Physics will create graphs of the object’s motion.
The labs also use an analysis app, also from Vernier, called Graphical. Graphical is currently free and available on Apple and Android. Graphical takes the data from Video Physics and creates more detailed motion graphs – x position, y position, x velocity, and y velocity vs. time – and also allows the option for students to analyze the graphs – get statistics, do a curve fit, and find an equation.
This is a complete set of labs for an entire motion unit that begins with an object moving in a straight line at a constant velocity and ends with predicting a landing spot for an object in projectile motion. As the students progress, they analyze different types of motion, each one building on the one before.
