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.

Easy-to-use

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.

Don’t buy

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.

Great app for $5, but also needs (free) Graphical Analysis app

Getting 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.
