The Galilean satellites are ellipsoidal in shape, due to having planetary mass, and so would be considered dwarf planets if they were in direct orbit about the Sun. The other four regular satellites are much smaller and closer to Jupiter; these serve as sources of the dust that makes up Jupiter's rings.The remainder of Jupiter's moons are irregular satellites, whose prograde and retrograde orbits are much farther from Jupiter and have high inclinations and eccentricities. These moons were probably captured by Jupiter from solar orbits. Characteristics[edit] Origin and evolution[edit] The relative masses of the Jovian moons.

Could High-Dive Jumpers Leap Over This Whole Pool? This is an older video from the World Championship in Dødsing. That’s about all I know except that it’s in Oslo, Norway. Watching this shows several very entertaining jumps. There are also a few jumps that look a little too close to the far edge of the pool. So, is it possible to run and jump from the high dive and hit the far end of the pool? Gathering Information After looking around on Google Maps, I found the location of the high dive. That’s about 16 meters from the end of the platform. Projectile Motion Yes, there is some guy jumping off a platform — in physics we would call this projectile motion even though he isn’t being “launched” like you might think. Since the only force is in the vertical direction, I can write the following two force equations. The acceleration in the horizontal (x-direction) would be zero and the acceleration in the vertical direction would be -g (or -9.8 m/s2). Since the x-velocity is constant, we can write the following: For the y-motion, we can write: Ok.
The Solar System: Space Gallery on Sea and Sky Our Solar System is a place of unimaginable beauty. Home to the Sun, eight planets, and a variety of smaller celestial objects, we have only recently been able to appreciate it fully. Thanks to the marvels of technology, robotic spacecraft have extended our view across vast distances, enabling us to see what was once hidden from our view. Join us now and examine some of the most recent images of our Solar System. The images in this gallery have been hand-selected by Sea and Sky for their visual beauty and represent some of the best views ever obtained of the Solar System.

Motion Mountain - The Free Physics Textbook for Dowload The Large Hadron Collider The Large Hadron Collider (LHC) is the world’s largest and most powerful particle accelerator. It first started up on 10 September 2008, and remains the latest addition to CERN’s accelerator complex. The LHC consists of a 27-kilometre ring of superconducting magnets with a number of accelerating structures to boost the energy of the particles along the way. Inside the accelerator, two high-energy particle beams travel at close to the speed of light before they are made to collide. The beams travel in opposite directions in separate beam pipes – two tubes kept at ultrahigh vacuum. Thousands of magnets of different varieties and sizes are used to direct the beams around the accelerator. All the controls for the accelerator, its services and technical infrastructure are housed under one roof at the CERN Control Centre. How many kilometres of cables are there on the LHC?

January 1, 2015. Preface For over a decade I have taught an introductory, undergraduate class, "Einstein for Everyone," at the University of Pittsburgh to anyone interested enough to walk through door. With each new offering of the course, I had the chance to find out what content worked and which of my ever so clever pedagogical inventions were failures. At the same time, my lecture notes have evolved. This text owes a lot to many. i i i
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. Also included is the minimum version of the Flash player that is required; the player is available free from The categories are: 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.

This reaction force creates a torque that, by itself, would make the helicopter spin in the opposite direction as the rotor. (This feature was updated on September 22, 2013.) Torque Check out this PBS video to use the concept of torque to explain how one dancer can balance on top of the head of another--and on point!
