Scorsese's 'Hugo' and the Mechanical Universe 2012-01-26T18:41:16Z This technique is called inertial confinement, because the fuel's inertia prevents it from escaping before significant fusion can take place. College Physics for AP Courses 2015-08-12T00:00:00Z Until now, inertial, feudal, and dispiriting bureaucracies that ignored human creativity were the only known way to bring people together to do complex things.

Laser fusion nears crucial milestone 2012-03-07T18:20:22.413Z A raised outside rail rotates a locomotive counterclockwise and helps fight off the clockwise rotation from the centrifugal inertial loading, at least a little bit. The Physics of Disaster: An Exploration of Train Derailments [Excerpt] 2013-07-29T17:15:10.223Z In the Philippines, the impact of inertial inflation to future inflation is quite strong. Philippines’ Tetangco Isn’t Ruling Out Further Rate Increase 2011-04-03T02:03:17Z Magnetic confinement and inertial confinement are the two methods being developed for heating fuel to sufficiently high temperatures, at sufficient density, and for sufficiently long times to achieve ignition. College Physics for AP Courses 2015-08-12T00:00:00Z With his laws of motion Newton introduced the notions of force and of inertial mass. Gravity, by George Gamow [Special Archive Article] 2011-03-04T13:45:00.433Z Glen Wurden, a plasma physicist at Los Alamos National Laboratory in New Mexico, agrees, saying that scientists working on inertial confinement should be wary of putting all their eggs in the laser basket. Laser fusion nears crucial milestone 2012-03-07T18:20:22.413Z If the centrifugal inertial loading is excessive, the locomotive begins to tip. The Physics of Disaster: An Exploration of Train Derailments [Excerpt] 2013-07-29T17:15:10.223Z A GPS system located the car on a map, while an inertial measurement unit tracked the car's speed and direction in case it lost GPS contact. Driving Blind at Daytona 2011-02-04T20:13:00Z Objects and systems have properties of inertial mass and gravitational mass that are experimentally verified to be the same and that satisfy conservation principles. College Physics for AP Courses 2015-08-12T00:00:00Z But the nature of gravitational interaction, and in particular the reason for the mysterious proportionality between gravitational mass and inertial mass, remained completely hidden for more than 200 years. Gravity, by George Gamow [Special Archive Article] 2011-03-04T13:45:00.433Z Researchers calibrated the models using a computer program, fine-tuning the flexibility, inertial properties and hydrodynamic resistance of each body segment until the models could simulate the pivot feeding motion seen in the videos. How the Sea Horse Got Its Curves 2011-02-01T23:15:00.293Z The locomotive’s weight and inertial load both exert a torque. The Physics of Disaster: An Exploration of Train Derailments [Excerpt] 2013-07-29T17:15:10.223Z Government agencies are famously inertial, and it remains to be seen how much they will embrace the contests and prizes. Government's new modus operandi for innovation: The Prize 2010-04-29T18:30:00Z This inertial mass of an object is a measure of how difficult it is to alter the uniform motion of the object by an external force. College Physics for AP Courses 2015-08-12T00:00:00Z The two began to talk, interrupting each other, incoherently outlining the Confusor and the various forces it exerted, and the—what Mike kept calling the inertial fish hook. Where I Wasn't Going He wondered how much damage one could do with a nearly weightless stone, then remembered that inertial mass was unaffected by gravitational fields, or the lack of them. The Dueling Machine The delicate accelerometers and inertial guidance components did all the piloting until the second stage kicked us loose. The Trouble with Telstar "You are, of course, aware of the problems inherent in the development of inertial systems," Marks began. The Electronic Mind Reader An inertial reference frame is any reference frame that is not itself accelerating. College Physics for AP Courses 2015-08-12T00:00:00Z Each proton and electron fitted itself more snugly against the north pole face and pushed with the entire force of its newly-imposed inertial pattern. Where I Wasn't Going The inertial gravities didn't bother me so much as the gyroscopic spin they put on the ship so we have a sort of artificial gravity to hold us against the curved floor. The Dope on Mars Morey pointed out the huge molecular power cylinder overhead, where the main power drive was located in the inertial center of the ship, or as near as the great space coil would permit. Invaders from the Infinite The main contribution of psychoanalysis and later psychodynamic schools is the understanding that self-identity is a dynamic, evolving, ever-changing construct - and not a static, inertial, and passive entity. Moral Deliberations in Modern Cinema A car traveling at constant velocity is an inertial reference frame. College Physics for AP Courses 2015-08-12T00:00:00Z Well inside the balloon, at the tip of the ruby barrel that was its heart, were located the boiler tubes that activated the self-centering inertial orientation servos which must remain operational at all times. Where I Wasn't Going The gravitating force between all molecules; the law of continuity; the inertial force of matter; the sublime facts of organic co-ordination and adaptation,--all these are recognized, analyzed, recorded, taught. Bits about Home Matters They are the inertial power - rather than the counterfist of reform. After the Rain : how the West lost the East Note that Newton’s laws of motion are only valid for inertial reference frames. College Physics for AP Courses 2015-08-12T00:00:00Z A car slowing down for a stoplight, or speeding up after the light turns green, will be accelerating and is not an inertial reference frame. College Physics for AP Courses 2015-08-12T00:00:00Z The crucial factor in determining whether a frame of reference is inertial is whether it accelerates or rotates relative to a known inertial frame. College Physics for AP Courses 2015-08-12T00:00:00Z Unless stated otherwise, all phenomena discussed in this text are considered in inertial frames. College Physics for AP Courses 2015-08-12T00:00:00Z All forces share certain common characteristics when considered by observers in inertial reference frames. College Physics for AP Courses 2015-08-12T00:00:00Z This allows us to view the motion as if M were stationary—in fact, as if from an inertial frame of reference placed on M —without significant error. College Physics for AP Courses 2015-08-12T00:00:00Z Finally, when the car goes around a turn, which is due to an acceleration changing the direction of the velocity vector, it is not an inertial reference frame.
