Interesting High-speed Video Clips Physics Flash Animations We have been increasingly using Flash animations for illustrating Physics content. This page provides access to those animations which may be of general interest. The animations will appear in a separate window. The animations are sorted by category, and the file size of each animation is included in the listing. In addition, I have prepared a small tutorial in using Flash to do Physics animations. LInks to versions of these animations in other languages, other links, and license information appear towards the bottom of this page. The Animations There are 99 animations listed below. Other Languages and Links These animations have been translated into Catalan, Spanish and Basque: En aquest enllaç podeu trobar la versió al català de les animacions Flash de Física. Many animations have been translated into Greek by Vangelis Koltsakis. Most animations have been translated into Hungarian by Sandor Nagy, Eötvös Loránd University.

Gear template generator This free online gear template generator is designed for making scale accurate paper gear templates which you can glue onto wood and then cut out with a bandsaw. I recommend printing the gears with an ink jet printer. Even cheap ink jet printers print very scale accurate but Not all laser printers are accurate. You can still access the old (pre 2015) Flash based gear geberator Getting the printout to scale correctly, avoiding cropping Different browsers print at different scales depending on browser type and printer configuration. Use an ink jet printer I recommend using an ink jet printer. Printing the gear templates To print the gear template, use the 'Print' button, instead of printing the web page from the browser. The gear generator program that I created and sell doesn't need the scale calibration, and can paginate across many pages for larger gears. Some notes about gear design and this gear template generator This gear template generator generates shapes for involute spur gears.

Conservation of Energy | Circus Physics | Classroom | Circus The aerial acrobatics of the Russian Barre routine require exquisite balance, timing, and years of training. That's not enough though; conservation of energy plays a big role as well. At the top of the jump, Anna's energy is entirely potential but as she falls, her energy turns kinetic. Landing on the bar, the energy changes form once more, stored as elastic energy in the bending bar. This unit explores the basics of these three common forms of energy. Watch the Video Questions to Consider While Watching the Video What forms of energy do you see? Digging Deeper As Anna jumps and lands on the bar, her energy changes forms multiple times, but notice that her total energy, the bar on the right, never changes. At the top of the jump, Anna's energy is entirely in the form of gravitational potential energy, P. P = mgh As she begins to fall back down, her velocity increases as her height decreases. K = ½mv² U = ½kd² Your Turn Use the concepts and formulas from this unit to figure out the following:

10 Strange Things About The Universe Space The universe can be a very strange place. While groundbreaking ideas such as quantum theory, relativity and even the Earth going around the Sun might be commonly accepted now, science still continues to show that the universe contains things you might find it difficult to believe, and even more difficult to get your head around. Theoretically, the lowest temperature that can be achieved is absolute zero, exactly ? One of the properties of a negative-energy vacuum is that light actually travels faster in it than it does in a normal vacuum, something that may one day allow people to travel faster than the speed of light in a kind of negative-energy vacuum bubble. One prediction of Einstein’s theory of general relativity is that when a large object moves, it drags the space-time around it, causing nearby objects to be pulled along as well. Relativity of Simultaneity Since this extra dimension is so small, only tiny objects, such as particles, can move along it. Antimatter Retrocausality

Description lanl.arxiv.org e-Print archive mirror 123D Fab! Cardboard Construction Kit This is the story of how I designed a cardboard construction kit and how a bunch of very clever people at Autodesk University 2011 used it to make things far cooler than I could ever have anticipated. I'll discuss the backstory of the construction kit, my thought process in designing it and what happened when it was unleashed on a test audience of designers, architects and engineers. The kit itself consists of an assortment of laser-cut cardboard pieces that can slot together in a regular, geometric fashion to form complex and weird structures. While the simplest components of the kits are just circles with slotted rims, the kits also contain a wide variety of decorative pieces (e.g. wings, hands, mustaches), mechanical components (e.g. wheels, gears, levers) and structural units (e.g. long beams, "peanut" shapes, semicircles) which can all be combined in countless ways. Here's one example of something that can be made with the kit, which is now available on the Instructables Store:
