'Video Physics brings physics video analysis to iPhone, iPod touch and iPad. 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. Open in Vernier Graphical Analysis for iPad or with your computer running Vernier's Logger Pro software. Open with Dropbox or Google Drive to store your data file in the cloud. Video Physics is perfect for physics students and instructors. 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.'
'Features of Vernier 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. • 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.'
