Vernier Video Physics vs Exoplanet Explorer

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 App Store featured: Staff Favorite, New and Noteworthy, and What's Hot! 2012 CODiE Awards Finalist - Best Educational Use of a Mobile Device 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.

Explore the universe of exoplanets — over 6,000 confirmed worlds orbiting distant stars, updated from leading scientific archives. Track new discoveries as they happen and dive into the data behind every planet. EXPLORE THE COSMOS Search, filter, and sort the complete catalogue of confirmed exoplanets. Find planets by discovery method, star type, orbital characteristics, or habitability potential. Every entry includes detailed scientific data from peer-reviewed sources. ATMOSPHERIC SPECTRA Browse JWST and Hubble transmission spectra for planets where atmospheric data is available. Toggle molecular overlays for CO2, CH4, H2O, CO and more to see which absorption features have been detected. 3D SYSTEM VIEW Step into a planetary system in 3D — see each planet's orbit around its host star with realistic shading and a visualisation of the habitable zone. On iPhone and iPad you can also place a system into your environment in AR. COMPARE WORLDS Analyze exoplanets side-by-side — or compare them with Solar System planets like Earth, Jupiter, and Mars. Compare sizes, masses, orbital periods, star properties, and habitability scores to understand what makes each world unique. HABITABLE ZONE VISUALIZATION See exactly where planets orbit within their star's habitable zone — the region where liquid water could exist. Identify potentially Earth-like worlds and understand the conditions for life beyond our solar system.
