Video Physics for iPad, iPhone, and iPod touch

Video Physics for iOS brings physics video analysis to the iPhone, iPod touch, and iPad.

Capture, Analyze, and Share.

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 the object 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.


  • Requires iOS 8.0 or later.
  • Compatible with iPhone, iPad, and iPod touch.

  • 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 GW 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

It’s a handy app, and if you teach High School Physics, then it’s highly recommended.

Video Tips

  • 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, iPod touch, and Android or Logger Pro software for Mac OS X and Windows.
