Report an issueVideo 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.

8 of 25Getting accurate results requires that you know what you’re doing, but if you do, then it’s great. The auto tracking is meh, but manually adding data points is quick and easy. Unfortunately, analyzing the data in this app is crap. Instead, download Vernier’s free Graphical Analysis app and import the data into that. Once the data is there, you can view x and y position and velocity data as well as do curve fitting. All in all, well worth the money for a physics classroom.
Actually very good! This app has very unique features I thought a mobile device couldn’t do! I could recommend to be able to add things the the tracking but it looks like you can draw if you track it on your finger!
Really old tech here. Doesn’t easily work - maybe on super simple applications like the ball drop example. The tracking is not usable for anything beyond the simple examples shown for a basic lab experiment.
The newest update has several bugs which make the app unusable. When you move the selector around the video controls disappear and cannot be brought back up. Please fix!
Great for school, athletics, etc.
I used this app for several months for teaching and now it crashes every time I try to open a video for analysis, the app crashes.
I am a physics teacher and love to use this app. It does a fantastic job at showing the motion of the object and then graphing the position vs time as well as velocity vs time. The use and manipulation of the app to plot points and set up your scale and origin is fantastic. My request (at to give it 5 stars) would be to allow you option to export the coordinate system with the video. Also, it wouldd be great if it would graph the acceleration vs time.
Fine if the app were free, but pretty unacceptable issues for a paid app. This app seems pretty easy to use which is great, but the inability to set the scale to something other than 1 m makes it very inflexible. You can’t really investigate what is happening if you are investigating anything smaller than a meter, and if you are looking at things much larger you can only set a scale of 1m which increases the uncertainty of the measurements. Furthermore, there is not an ability to do time delay which makes this even less useful. You should be able to set the time origin in sync with the first video analysis point. These things really need to get fixed.
