Vernier Video Physics

There needs to be a way to show individual data points without having to export the data to another app. I would also put a single graph on each screen instead of 2.

This app is a useful tool for kinematics, especially projectiles. Advantages: This is a lot better than the old-school method of tracing motion on overheads taped to a TV screen. Simply take a video, indicate the location of your axes and a scale object, and mark the location of the moving object in each frame. (Simple, but tedious.) Then you get nice kinematics graphs. Shortcomings: It would be nice to be able to compensate for camera movement (by, say, indicating the location of fixed objects) and there seems to be no way to take high-speed videos to analyze fast objects. (One can use another app to do that and import the video, but that's an extra step, and an extra purchase.)

With an iPad, this app is pretty awesome! Exporting to Logger Pro is even better! I'm probably still on the learning curve, but I haven't figured out how to maintain the measurement reference. Still, this is going to be a staple in my physics class!

This app badly needs Graphical Analysis app for non-iPad users, so they can take full advantage of this app! Without it this app is pretty much pointless if you don't own an iPad.

Easy enough to use for all of my students and a whole lot simpler than trying to install software on the school computers. Tried it for one activity using my personal iPad and my students decided that they would like to have the app on their iPods and iPhones. This app helps to skip past the tedium of measuring and graphing and moving directly to analyzing data. I haven't learned how to have students share videos and graphs without using the school WiFi network but this seems to be a limitation of the platform and not the app.

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.

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.

Tracking need to be done with a special care. Make video that way you have high contrast between tracking object and the background
