Video Physics brings automated object tracking and video analysis to iPhone, iPod touch, and iPad. Capture video of an object in motion, then tap to track automatically. Video Physics instantly creates trajectory, position, and velocity graphs for the object.
Video Physics is perfect for science students and instructors. Perform on-the-go analysis of interesting motion. 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.
Features of Video Physics:
• Capture a new video using the built-in camera, choose a video from your Photo Library, or use one of our sample videos
• Track an object automatically or manually add points to the video 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 video with points
• 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's Graphical Analysis app
Quotes from physics teachers:
"Just played with new Vernier video physics app on iPhone - it ROCKS! I remember the day when this would've cost thousands of dollars to do ." Mark Hines @mhines, teacher
"You should check out Vernier's Video Physics app. Students can email video analysis data to Logger Pro; very cool!!" @willkomme, physics teacher

Hints for taking useful videos:
• Objects that are very different than their background (black/white) work best for automated tracking. It is also helpful to use a background with uniform color and shading. See our sample videos for examples.
• Do not move the camera. Analysis assumes the camera is fixed in position.
• The object in motion should remain approximately in a plane perpendicular to the viewing direction.
• Place an object with known dimensions, such as a meter stick, in the same plane as the motion. Use this to scale the video.
Video Physics is intended for use in science education. The video analysis done in Video Physics provides a useful technique for studying two-dimensional kinematics. You can do even more with Vernier's Graphical Analysis app for iPad, iPhone, and iPod touch or with Logger Pro software for Mac OS X and Windows.

Ratings and Reviews
Video analysis without going to the computer lab.
Easy enough to use for all of my students and a whole lot simpler than trying to install software on the school computers. Tried it for one activity using my personal iPad and my students decided that they would like to have the app on their iPods and iPhones. This app helps to skip past the tedium of measuring and graphing and moving directly to analyzing data.
I haven't learned how to have students share videos and graphs without using the school WiFi network but this seems to be a limitation of the platform and not the app.
Needs to show data points
There needs to be a way to show individual data points without having to export the data to another app.
I would also put a single graph on each screen instead of 2.
Decent little app
This app is a useful tool for kinematics, especially projectiles.
This is a lot better than the old-school method of tracing motion on overheads taped to a TV screen. Simply take a video, indicate the location of your axes and a scale object, and mark the location of the moving object in each frame. (Simple, but tedious.) Then you get nice kinematics graphs.
It would be nice to be able to compensate for camera movement (by, say, indicating the location of fixed objects) and there seems to be no way to take high-speed videos to analyze fast objects. (One can use another app to do that and import the video, but that's an extra step, and an extra purchase.)
