Vernier Software & Technology has announced the winners of its Video Physics Contest, a competition created to mark the launch of Vernier's Video Physics app for iPhone, iPod touch and iPad. The winning entries demonstrated both creativity and innovation by using video to demonstrate the science concepts behind many everyday occurrences, from the motion of a supermarket checkout conveyor belt to the flow of a creek.
The innovative video projects shared by winners illustrate the utility of Vernier's Video Physics application, a new iOS application that can be used by educators and students to take video of an object in motion, mark object position frame by frame, and set up the scale using a known distance. Examples of the use of Video Physics in the field include measuring the trajectory of a free throw shot, the motion of a child's swing, and the velocity of a car. Video Physics draws trajectory, position, and velocity graphs for any moving object and is an excellent tool for teaching two-dimensional kinematics. Video Physics has been featured as "New," "Noteworthy," and "What's Hot" in the iTunes App Store and works well with the HD video recording features of the new iPad and iPod touch.
Three winners were chosen to receive an iPod Touch with HD video recording. These prizes were awarded to:
- The team of Rex Rice, Gabe de la Paz, Rob Laux, Ryan King, and Jennifer Adams, from Clayton High School, in Clayton, MO. Together they created a video examining the uniform circular motion of a hoverpuck anchored by a string. Students are able to see what happens when the centripetal force is removed by a blowtorch.
- Bobby Quimpo, of West Central High School in Francesville, IN, who used video to observe mathematics in the motion of a steel can.
- Dale Basler, of Appleton East High School in Appleton, WI, who investigated physics in the grocery store. Dale chose the unique perspective of the conveyor belt itself for his iPhone camera, creating a frame of reference in which the supermarket counter appeared to be in motion.
Vernier also chose second place winners who each received a $25 iTunes gift card. These prizes were awarded to:
- Tom Pasquini, of Kimball Union Academy in Meriden, NH. Tom analyzed the puzzling nature of a bouncing ball that retraces its own path.
- Jennifer Meyer of Parkway Central High School in Chesterfield, MO, who observed and analyzed the physics of a dive.
- Chris Carman and the environmental partnership between Theodore Roosevelt High School and Davey Elementary School in Kent, OH. The team used Video Physics, an iPhone, and an orange to measure the rate of creek flow in their local watershed.
- Bobby Quimpo, of West Central High School in Francesville, IN, whose students recorded video while balancing a meter stick on one end. Using video analysis, students were able to track the center of mass and reinforce the fundamental nature of trajectory motion.
Teachers and students are encouraged to visit the Video Physics Contest web gallery to view and download the winning entries, and to learn more about Video Physics for iOS: www.vernier.com/ios/contest.html. These videos will also be available to users of Video Physics in a free update via the iTunes App Store.
