Greg Jacob blogged about the ease and usefulness of Vernier Video Physics:
As a testament to this app’s ease of use, I produced a useful video and graph within minutes of first opening the app, without reading any sort of instruction manual. Then, I showed my 8 year old how it worked. He spent a couple hours taking and analyzing videos, proudly showing his grandmother that the dropped ball was going 600 cm/s, but the dog’s nose only went 150 cm/s. I approve.
