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.

User Reviews

Users largely praise the app for quick data capture, instant analysis, and helpful graphs in classroom and athletic settings, but consistently flag price, reliability issues after updates, tracking limitations, export options, and scaling/timing constraints as major drawbacks.

Pros

Quick data capture and instant analysis; the app does the math for you.
Excellent classroom tool that reduces lab time and helps students understand motion.
Clear graphs (position and velocity vs time) with an intuitive tap-to-track workflow.
Mobile-friendly workflow for capturing video and analyzing on the go.

Cons

Expensive; many users feel it is not worth the price.
Bugs and crashes after updates; controls or video playback can disappear.
Auto-tracking is unreliable; manual tracking is tedious and not always accurate.
Poor/export-limited data sharing; hard to export to Excel/Numbers or share results.
Scale and timing limitations; can only set a 1 m scale and lacks time origin or delay features.

Very hard to use, expensive for what? Overall a mid product and not worth my money

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.

I’m a chemistry teacher who uses many Vernier products in class and I also coach pole vault. I started using this with my athletes to analyze their run so I can show them what I see by eye. I just really wish we could change the axis options as x velocity vs x position would help show them more accurately the set-up at take-off. This would greatly improve efficiency and effective coaching as I need to export into the graphical analysis app. This change would speed up my analysis! As others mention, the tracking feature doesn’t work well for me either as I’m analyzing running mechanics.
