OThe Physics of Airplanes Background: At any given moment‚ roughly 5‚000 airplanes crisscross the skies above the United States alone‚ amounting to an estimated 64 million commercial and private takeoffs every year (source: NATCA). Considering the rest of the world ’s flight activity‚ the grand total is almost incalculable. In order to understand how airplanes fly‚ we must break down the parts of an airplane and understand the physics behind the airplanes most important components: the engine/propeller

IMPORTANCE OF SOCIAL MEDIA IN OUR LIFE “Paper is no longer a big part of my day. I get 90% of my news online‚ and when I go to a meeting and want to jot things down‚ I bring my Tablet PC. It’s fully synchronized with my office machine‚ so I have all the files I need. It also has a note-taking piece of software called OneNote‚ so all my notes are in digital form” are the words of Bill Gates Social media plays an important role in today’s world. It is impossible to imagine a day without internet

Many people are unable to make a connection between the numbers on the paper and what they do on a daily basis. People use a lot of what they were taught in school without even thinking much about it. Math is all around us‚ even in the kitchen. When cooking a meal‚ we sometimes checks the recipe to measure the portion or double-check the ratio of ingredients. Choosing between a cup of sugar or a half cup is a mathematical decision. Even setting and checking the timer to make sure the dish cooks

Chapter 25 Electrical Power and Domestic Electricity Checkpoint (p.197) 1. The heating effect of current increases with the applied voltage across the wire. Microscopically‚ when a voltage is applied across the ends of a metal wire‚ an electric field is set up between the ends. The free electrons are accelerated by the field and collide frequently with the metal ions in the wire. Thus‚ some energy is transformed into the internal energy of the wire. When the applied voltage increases‚ the electric

computers. Virtually‚ computers which pressure most people’s life are considered as the most important technological achievement of the XXI century. Using computers‚ we can make or solve most of difficult things which are hardly completed without their hands. Because of these different varieties of abilities‚ computers have been creating many noticeable achievements in most of societies’ fields especially medicine‚ education‚ and usual life. In other words‚ these three fields also are computers’ influences

GRAVITATION Kepler’s Laws Towards the end of the sixteenth century‚ Tycho Brahe collected a huge amount of data giving precise measurements of the position of planets. Johannes Kepler‚ after a detailed analysis of the measurements announced three laws in 1619. 1. The orbit of each planet is an ellipse which has the Sun at one of its foci. 2. Each planet moves in such a way that the (imaginary) line joining it to the Sun sweeps out equal areas in equal times. 3. The squares of the periods

Physics in Sports Introduction Billiards‚ Pool or 8 Ball are the names given to this game. For many of us 8 Ball is a game that we play at friends’ place or at pool houses‚ pubs and a good many other places. But when you are playing 8 Ball you would never really think about physics would you? But it is there‚ and it is in play everytime the cue hits the ball to make it curve‚ everytime you jump the ball over another or bounce it around the cushioned sides to get the white ball
