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.

Great potential for five stars
SeeNick
I've been using LoggerPro for about six or seven years, so I knew pretty much what to expect. For the most part I got it. My 2g Touch crashed the ap the first time I tried to analyze, but worked great from then on out. The graphs are entirely recognizable on their famous basketball video. I'm sure a little more practice would make me better, but it is a little difficult to see the crosshairs against the background, especially that wooden paneling. I tried the baseball video also, but couldn't see the ball. I would suggest two improvements for five stars; 1) zoom in capability (I realize the difficulty here) and 2) crosshairs that can color change to make them easier to see in more situations. I'm so psyched about this ap though, despite the room for improvement. I'm definitely going to be spreading the word.
Great classroom tool from Vernier!
Kenneth Magno
This is a great concept from Vernier. I have loved using the LoggerPro video analysis with my class for years. The only issue I have with the software is that targeting and clicking with a second finger is a bit odd since you can't see your targeted object since your finger covers it. It might be nice if a button was added to select the target after you already know you've got it in the crosshairs. 4/5
No zoom
James Xu
No zoom function. This makes plotting points to be very inaccurate for small objects.
Not intuitive.
PacificLucy
My students figure out how to use it. I can't figure it out. Not intuitive.
For small fingers
Balrog62
The small screen makes plotting points difficult. Also, there appears to be no way to delete a point & try to plot it again. Small fingers & a steady hand are a must. Otherwise, it's a great little tool.
Very nice app!
iLovMyiPhone
Very nice app for video analysis. I hope this is the first step from vernier to integrate their hardware (sensors) with iPad and iPhone software
Very cool and promising

For anyone familiar with Vernier's Logger Pro or LabQuests, you get the same kind of quality that you expect from them in this app. The app itself is pretty straightforward - record video, place the origin, set your reference length (e.g. a meter stick), and then start adding points for whatever you're measuring. The fact that it's portable in your pocket with your iPhone/iTouch more than makes up for its shortcomings; I don't teach physics any more but I've used this to determine the flow rate of a creek with a floating orange (very close to their results from their flow rate sensor) in Environmental Science and to analyze the exit velocity of the diet coke + mentos reaction as a discrepant event in Chemistry. It's a lot of fun with kids, too - just record them running by and they think it's the coolest thing ever. There are a few shortcomings to the app that would make it absolutely spectacular: - no in-app data analysis like in the LabQuest (slope, average, etc) - no data table just showing the raw data - deleting a bad data point is a pain, maybe there could be an option to confirm each point? - a zoom function would be absolutely wonderful for higher precision - the origin grid gets in the way sometimes when you're adding points, maybe it could be turned off temporarily? These are minor points compared with the capability the app gives you - you can record an event and generate your graph and cmbl file in ten minutes, when it would take much longer using an external camera and other programs. Definitely a must-have for iPhone/iTouch owning science teachers who want to make science education more hands-on!
Great app for education!
Eric Sci & Tech
Very easy to use; good data; easy to transfer data and analysis to Facebook or to email. Students loved using it. Good job Vernier!
Vernier, U Could Do Better!
TNTbaba
0) Good start of an App! 1) The major disappointment with this App is the lack of the graph analysis features (such curve fitting, stats., examining, and deriving calculus items) that made LoggerPro software the jewel of Physics labs. Thus, the introduction of the afore mentioned items in future versions of the App are a must in order fro the App to be educationally viable. 2) The user interface is a bit clumsy especially for adults and the two-finger tapping method induces point location errors; a much more accurate method need to be devised instead. 3) Knowing Vernier, there is hope that better days are awaiting this App! Salam!
Will not mirror.
Peaceloveandphysics
This app would be worthwhile to a teacher if you could mirror to an LCD. I have an iPad 2 and everything mirrors accept this app. There is no benefit unless my students and I can analyze a captured video together.
