The Biomechanics of Good Running | Playbook
AUSTIN, Texas — If you’re a runner and you can’t extend your hip well behind you on your stride, Jay Dicharry has bad news: You’re never going to be a great runner. [bug id="sxsw2012"]This doesn’t mean you should hang up your shoes. You can still run, and run well, but not everyone can attain the ideal stride needed to be a truly great runner. Dicharry is the director of the Speed Performance Clinic and the Motion Analysis Lab Coordinator At The University Of Virginia. In discussing the biomechanics of running here at South by Southwest Interactive he recalled his Louisiana roots to emphasize his point. “I’m from New Orleans, and there’s great food there,” he said, by way of understatement. Most runners don’t extend their hips, Dicharry said. Along with a lack of hip extension, overstriding is one of the biggest sins. “Look at their gait,” he said. Only Andrews maintained textbook form for the whole race, finishing first in 1:44.71, just .01 off the meet record. Third, kneel on one knee.

E-mail: wochristian@davidson.edu Scientists routinely use computer modeling and computation in innovative research, including predicting the nature of He4 at extremely low temperatures and the impact of human activity on climate. Why does computer-based modeling remain absent from many educational programs? The Open Source Physics (OSP) project, www.compadre.org/osp/, seeks to enhance computational physics education by providing a central Web site containing computer modeling tools, simulations, curricular resources such as lesson plans, and a computational physics textbook that explains the pedagogic simulations' algorithms (1). Students who learn physics concepts via static pictures may be led to construct incomplete or incorrect mental models that hamper their understanding of physical concepts. Dynamic modeling.

Newtons Laws
Force When forces are unbalanced, objects accelerate. But what factors affect the amount of acceleration? Free-Body Diagrams The Free-Body Diagrams Interactive is a skill-building tool that presents users with 12 physical situations for which they must construct free-body diagrams. Rocket Sledder Created by our friends at Nerd Island Studios, this Interactive illustrates the effect of friction, air resistance, and applied force upon a sledder. Skydiving Created by our friends at Nerd Island Studios, this Interactive allows the learner to explore the motion of an object falling under the influence of air resistance. You might have wondered why you get that queasy feeling in an elevator as you start up and slow down. Everyone is fascinated by pulleys.

Accelerometer
Created by our friends at Nerd Island Studios, the Accelerometer Interactive allows learners to collect data of velocity as a function of time for their mobile device. If the device has a built-in accelerometer, the Accelerometer Interactive will be able to plot an acceleration vs. time graph as the device moves. That's both nifty and risky. Launch Interactive Users are encouraged to open the Interactive and explore. Learners and Instructors may also be interested in viewing the accompanying Notes page. The Physics Classroom would like to thank Nerd Island Studios for creating this Interactive and offering it to be part of our collection of Physics Interactives. (DISCLAIMER: Neither The Physics Classroom nor Nerd Island Studios will pay for phones and tablets that were broken while using this Interactive.

How Nanotechnology Works
There's an unprecedented multidisciplinary convergence of scientists dedicated to the study of a world so small, we can't see it -- even with a light microscope. That world is the field of nanotechnology, the realm of atoms and nanostructures. Nanotechnology is so new, no one is really sure what will come of it. Even so, predictions range from the ability to reproduce things like diamonds and food to the world being devoured by self-replicating nanorobots. In order to understand the unusual world of nanotechnology, we need to get an idea of the units of measure involved. As small as a nanometer is, it's still large compared to the atomic scale. In a lecture called "Small Wonders:The World of Nanoscience," Nobel Prize winner Dr. In this article, we'll learn about what nanotechnology means today and what the future of nanotechnology may hold. In the next section, we'll learn more about our world on the nanoscale.
Graph That Motion
The Graph That Motion Interactive consists of a collection of 12 challenges. Each challenge presents learners with an animated motion of a car. After viewing the motion, one must match the motion to the corresponding position-time or velocity-time graph. Feedback is immediate and mulitple attempts to get the matching graph correct are allowed. Launch Interactive This Interactive is self-supporting; there is no suggested exercise. Learners and Instructors may also be interested in viewing the accompanying Notes page.
