Description

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

Vernier’s Video Physics app is slick. - Ryan Bretag @ryanbretag, teacher and administrator

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.

Version 1.2

Thanks for all your support and for making Vernier Video Physics one of the most popular educational apps for science!

With this update, iPad users can perform data analysis on their video data with enhanced integration with Vernier Graphical Analysis™!

Download Graphical Analysis from the App Store, then use the "Open data in…" function to:

☞ Make selections and annotations.
☞ Calculate statistics such as max, min, mean.
☞ Perform fits, including linear, quadratic and more.
☞ Create custom high-resolution graph images for email and export.

⚠ Please note: Due to changes in the Facebook interface, this version of Video Physics does not support sharing directly to Facebook. You can still post to Facebook by saving to the Camera Roll first and using the Facebook app or web interface. If in-app support of Facebook is important to you, please skip this update and let us know at:
connectedscience@vernier.com

Additional features:

• Open data files in Dropbox or Google Drive to store and retrieve them. Later use the files with Graphical Analysis or Logger Pro.

• Support for 4-inch display of iPhone 5 and 5th-generation iPod touch. :)

• New high-resolution controls for iPad with retina display. :)

• Bug fixes and performance improvements for import and export, adding and deleting points, frame advance, adjustment of axes, and more.
