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. The video analysis done in Video Physics provides a useful technique for studying two-dimensional kinematics. Video Physics is intended for use in science education. Place an object with known dimensions, such as a meter stick, in the same plane as the motion.The object in motion should remain approximately in a plane perpendicular to the viewing direction.Analysis assumes the camera is fixed in position. It is also helpful to use a background with uniform color and shading. Objects that are very different than their background (black/white) work best for automated tracking.Ryan Bretag teacher and administratorĪpp Store featured: Staff Favorite, New and Noteworthy, and What's Hot!Ģ012 CODiE Awards Finalist - Best Educational Use of a Mobile Device Students can email video analysis data to Logger Pro very cool!!" physics teacher "You should check out Vernier's Video Physics app. "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 teacher Open data files directly in Vernier's Graphical Analysis app.Email the video and data for further analysis in Vernier's Logger Pro software for OS X and Windows.View graphs of trajectory and x/y position and velocity.Optionally set coordinate system location and rotation. Set the scale of the video using an object of known size.Track an object automatically or manually add points to the video frame.Capture a new video using the built-in camera, choose a video from your Photo Library, or use one of our sample videos.x as well as the x and y position and velocity as a function of time. Video Physics will display the path of the ball and provide graphs of y vs. Or, take a video of a basketball free throw shot. Measure the velocity of a child's swing, a roller-coaster, or a car. Perform on-the-go analysis of interesting motion. Video Physics is perfect for science students and instructors. Video Physics instantly creates trajectory, position, and velocity graphs for the object. Capture video of an object in motion, then tap to track automatically. Although they do not specifically mention Graphical Analysis Pro, these experiments offer excellent opportunities to incorporate the app into your teaching.Video Physics brings automated object tracking and video analysis to iPhone, iPod touch, and iPad. On August 1, we will be offering a free webinar that highlights ways to use the app’s advanced features with some of our most popular Go Direct physics sensors to explore force, motion, and sound.Īhead of the webinar, I’m sharing three experiments that are great for hands-on physics learning. The app works on a wide variety of devices and platforms, including Chromebooks™, cell phones, and iOS. Graphical Analysis Pro also promotes accessibility, which is great for educators and students alike. For example, I would have loved to have been able to do live data sharing and use FFTs with my students. Some of the app’s features were inspired by my experience as a high school physics teacher. 130 m/s 2 in the direction of the second child’s push. (a) The system is the child in the wagon plus the wagon. Energy, acceleration, and simple harmonic motion are just a few important physics principles for students to learn-and using the Graphical Analysis Pro app with our Go Direct ® sensors can help bring these abstract scientific concepts to life. (b) The acceleration is not one-fourth of what it was with all rockets burning because the frictional force is still as large as it was with all rockets burning.
