HyperPhysics Concepts About HyperPhysics Rationale for Development HyperPhysics is an exploration environment for concepts in physics which employs concept maps and other linking strategies to facilitate smooth navigation. For the most part, it is laid out in small segments or "cards", true to its original development in HyperCard. 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 Physics Classroom Topics 1-D Kinematics The motion of objects in one-dimension are described using word, diagrams, numbers, graphs, and equations. Newton's Laws "The Elements". A Flash animation The Periodic Table The periodic table of the chemical elements (also periodic table of the elements or just the periodic table) is a tabular display of the chemical elements. Although precursors to this table exist, its invention is generally credited to Russian chemist Dmitri Mendeleev in 1869, who intended the table to illustrate recurring ("periodic") trends in the properties of the elements. The layout of the table has been refined and extended over time, as new elements have been discovered, and new theoretical models have been developed to explain chemical behavior.
Atom Atoms are small enough that classical physics gives noticeably incorrect results. Through the development of physics, atomic models have incorporated quantum principles to better explain and predict the behavior. Every atom is composed of a nucleus and one or more electrons bound to the nucleus. The nucleus is made of one or more protons and typically a similar number of neutrons (none in hydrogen-1). Charges and Fields - Electric Charges, Electric Field, Electric Potential Topics Electric Field Electrostatics Equipotential Electrostatic Potential Electric Charges Voltage Description Arrange positive and negative charges in space and view the resulting electric field and electrostatic potential. Plot equipotential lines and discover their relationship to the electric field. Create models of dipoles, capacitors, and more!
Black hole binge could test general relativity - space - 03 May 2013 CRACKS in Einstein's theory of relativity could be evident at the heart of our very own galaxy. If new calculations are correct, the enormous black hole that sits at the core of the Milky Way should have Saturn-like rings that offer a safe haven from its irresistible gravitational pull. Einstein came out with his theory of general relativity in 1916. It describes how the effects of gravity emerge from the way space-time is shaped. It has passed every test thrown at it – including the latest, this week – but many physicists still believe general relativity has a chink in its armour.
Problem of Reciprocity Back to main course page John D. Norton Department of History and Philosophy of Science University of Pittsburgh Background reading: J. Schwartz and M. MythBusters Archive (Appropriate for Grades 6-12): MythBusters Live MythBusters Jamie Hyneman and Adam Savage shared their experiences as they make experimentation come alive through this dynamic presentation about science behind the exhibit. The interactive exhibit, created by Discovery Communications and Exhibits Development Group (EDG), in partnership with the Museum of Science and Industry in Chicago, helps inspire learning beyond the walls of the classroom.
Secret Worlds: The Universe Within - Interactive Java Tutorial Secret Worlds: The Universe Within View the Milky Way at 10 million light years from the Earth. Then move through space towards the Earth in successive orders of magnitude until you reach a tall oak tree just outside the buildings of the National High Magnetic Field Laboratory in Tallahassee, Florida. After that, begin to move from the actual size of a leaf into a microscopic world that reveals leaf cell walls, the cell nucleus, chromatin, DNA and finally, into the subatomic universe of electrons and protons. Once the tutorial has completely downloaded, a set of the arrows will appear that allow the user to increase or decrease the view magnitude in Manual mode.
