	NationMaster - Encyclopedia: Inertial reference frame
		In physics, an inertial frame of reference, or inertial frame for short (also descibed as absolute frame of reference), is a frame of reference in which the observers move without the influence of any accelerating or decelerating force.
		Frames of reference are especially important in special relativity, because when a frame of reference is moving at some significant fraction of the speed of light, then the flow of time in that frame does not necessarily apply in another reference frame.
		An accelerated frame of reference is often delineated as being the "primed" frame, and all variables that are dependent on that frame are notated with primes, e.g.

	Inertial frame of reference - Biocrawler
		All reference frames that move with constant velocity and in a constant direction with respect to any inertial frame of reference are members of the group of inertial reference frames.
		The group of inertial frames of reference is the only group of frames of reference in which the same laws of motion hold.
		Special relativity not only identified the Lorentz transformations as the appropriate transformations between inertial frames of reference, it also brought the perception that the 'laws holding good' for all members of the group of inertial frames of reference also includes the laws of electrodynamics, not just the laws of kinematics.

	Space and Time: Inertial Frames (Stanford Encyclopedia of Philosophy)
		A “frame of reference” is a standard relative to which motion and rest may be measured; any set of points or objects that are at rest relative to one another enables us, in principle, to describe the relative motions of bodies.
		A frame of reference is therefore a purely kinematical device, for the geometrical description of motion without regard to the masses or forces involved.
		Newton's Corollary VI said that the inertial frame we construct by this procedure is effectively indistinguishable from one in which all the bodies are undergoing equal and parallel accelerations caused by some force that acts equally on all of them; the equivalence principle asserts that gravity is such a force.

	Frame of reference Summary
		Alfred's frame of reference is considered an inertial frame of reference because he is not accelerating (ignoring effects such as Earth's rotation and gravity).

	PlanetPhysics: reference frames in newtonian physics
		That is, in an inertial reference frame, motion can result only from forces acting upon the body, and not through the system of coordinates that have been chosen to characterise the system.
		An inertial reference frame is one that moves with constant velocity relative too all objects that are not subject to a net force.
		This is version 1 of reference frames in newtonian physics, born on 2006-07-20.

	Inertial and Noninertial Frames of Reference
		In an inertial frame of reference, which the surface of the earth approximately is, the bowling ball obeys Newton's first law.
		In this frame of reference, it is the truck that appears to have a change in velocity, which makes sense, since the road is making a horizontal force on it.
		Any frame of reference in which the ball appears to obey Newton's first law is then a valid frame of reference, and to an observer in that frame, Mr.

	Inertial frame of reference - Wikipedia, the free encyclopedia
		Hence, within the inertial frame, an object or body accelerates only when a physical force is applied, and (following Newton's first law of motion), in the absence of a net force, a body at rest will remain at rest and a body in motion will continue to move uniformly —ie.
		A fundamental principle of all physics is the equivalence of inertial reference frames.
		By contrast, bodies are subject to so-called fictitious forces in non-inertial reference frames; that is, forces that result from the acceleration of the reference frame itself and not from any physical force acting on the body.

	INERTIAL FRAMES IN SR
		One of the often quoted features of relativity is that it eliminates the concept of privileged coordinate frames, and that all frames are on an equal footing for observing and formulating the "laws of nature".
		Therefore, the idea of inertial frames is extended beyond the classic model to allow a particular type of relative motion (i.e., uniform translational motion) between inertial frames.
		Even though Special Relativity conceded that "inertial frames" when considered as a class had a privileged status, it emphasized that all coordinate frames in that class had the equal right to consider themselves as being stationary(fixed, motionless) and the other inertial frames to be in motion with respect to them.

	Non-inertial Frame of Reference 1
		Below is a VRML animation of a non-inertial frame of reference similar to that which would be experienced in an elevator ride.
		This is an acceleration, and the elevator is again a non-inertial frame of reference.
		Such an elevator ride is an excellent example of a frame of reference that changes from an inertial frame of reference to a non-inertial frame of reference as the speed of the velocity changes from a constant value to a changing value respectively.

	Time Supplement [Internet Encyclopedia of Philosophy]
		A reference frame in which star motion is ignored and the stars are assumed to be at rest is approximately an inertial reference frame and is often adequate for many purposes.
		Consider the inertial frame of reference in which each observer is at rest in his or her own frame.
		Inertial frames can have global coordinate systems, but if we are working with general relativity where we cannot assume inertial frames, then the best we can do is to assign a coordinate system to a small region of spacetime where the laws of special relativity hold to a good approximation.

	Determining Absolute Motion Between Inertial Frames of Reference - Page 6 - SciForums.com
		The Earth's surface is stationary in the ECEF frame, and moving at 463m/s (at the equator) in the ECI frame.
		In this frame, clocks on the surface of the Earth (the surface mathematically modelled by WGS-84) are synchronized with the hypothetical clock at the center of the Earth.
		In this reference frame, the discrepancy is due the the different form of the laws of physics - specifically, the speed of light from east to west is faster than the speed of light from west to east.

	Accelerated reference frame Summary
		From the point of view of the interior of the car, an accelerating reference frame, there is a fictitious force pushing the passenger backwards, with magnitude equal to the mass of the passenger times the acceleration of the car.
		From the viewpoint of an inertial reference frame stationary with respect to the road, the car is accelerating toward the center of the circle.
		From the viewpoint of a rotating frame, moving with the car, there is a fictitious centrifugal force that tends to push the car toward the outside of the road (and the occupants toward the outside of the car).

	2 Reference Frames and the Sagnac Effect (Site not responding. Last check: )
		Although the ECEF frame is of primary interest for navigation, many physical processes (such as electromagnetic wave propagation) are simpler to describe in an inertial reference frame.
		A ``Conventional Inertial Frame'' is frequently discussed, whose origin coincides with earth's center of mass, which is in free fall with the earth in the gravitational fields of other solar system bodies, and whose z -axis coincides with the angular momentum axis of earth at the epoch J2000.0.
		For example, from the inertial frame it appears that the reference clock from which the synchronization process starts is moving, requiring light to traverse a different path than it appears to traverse in the rotating frame.

	Is the relativity principle an unquestionable concept of physics ?
		The equivalence of all "inertial" frames, would imply that, at the instant they meet, the time indicated by the clocks A and B would be identical.
		Thus, to each reference frame to which it is attached, corresponds, for a definite body, a definite kinetic energy (independent of the speed of other bodies) which implies a hierarchy between the different reference frames and thus, supposes (as we have already seen) the existence of a fundamental inertial frame.
		We therefore remark that the extension of the relativity principle to electromagnetism, implies the relativity of simultaneity and the reference to a four dimensional space-time.

	Sample Chapter for Mermin, N.: It's About Time: Understanding Einstein's Relativity.
		If you want to identify an inertial frame of reference as "the frame of reference of the ball," you must be sure to specify whether you mean the inertial frame in which the ball was stationary before 12, or between 12 and 1, or after 1.
		The frame we need is clearly the one that moves at 50 f/sec in the same direction as the ball, since in that frame of reference the ball is stationary.
		We wish to examine the initial situation in a frame of reference in which the big ball is stationary, so we must now view the collision in the frame of a train moving, with the big ball, at 10 f/sec to the left, as shown in figure 1.6.

		Inertial frames of reference are relevant to Newtonian relativity and Einstein's special theory of relativity.
		However, the assumption of constant progression of proper time in all frames of reference is replaced by the assumption that the speed of light is constant, and that this is equally true for every inertial observer.
		In another frame of reference the additional kinetic energy is that corresponding to the total mass and the speed of the center of mass.

	Flogging a Pink Unicorn
		It follows from the definitions of inertial frames and their equivalence that the centre of mass of an isolated system of bodies is at rest in an inertial frame.
		The Einstein equivalence principle states that in a local inertial reference frame the outcome of any non-gravitational experiment is independent of the velocity of the frame or its position in spacetime and that the laws of nature are those of special relativity.
		Although in relativity, preferred inertial frames are rejected, the Cosmic Microwave Background (the afterglow of the Big Bang) is taken as a special reference, and is interpreted as the rest frame of the universe.
