Name: Vernier Video Physics

What is it? A 2012 CODiE Awards Finalist for ‘Best Educational Use of a Mobile Device,’ Video Physics brings physics video analysis to iPhone, iPod touch and iPad. Users can take a video of an object in motion, mark its position frame by frame, and set up the scale using a known distance. Video Physics then draws trajectory, position, and velocity graphs for the object. Share video, graphs and data via the Camera Roll, eMail, and iTunes. Perform on-the-go analysis of interesting motions. Measure the velocity of a child’s swing, a roller-coaster, or a car. Or, take a video of a basketball free throw shot. Video Physics will display the path of the ball and provide graphs of Y vs X as well as the X and Y position and velocity as a function of time.

Best for: Students and physics instructors.

Requirements: Compatible with iPhone, iPod touch, and iPad. Requires iOS 5.1 or later. This app is optimized for iPhone 5.

Price: $4.99

Rated: 4+

Features: Capture a new video using the built-in camera, choose a video from your photo library, or use one of our sample videos; mark the position of one object, frame by frame; set the scale of the video using an object of known size; optionally set coordinate system location and rotation; view graphs of trajectory, and x/y position and velocity; export the marked video to your Photo Library; graphs are appended to video; eMail the video and data for further analysis in Vernier’s Logger Pro software for OS X and Windows; open data files directly in Vernier Graphical Analysis for iPad; open data files in Dropbox or Google Drive to upload to the cloud.
