  motion. The Columbia Encyclopedia, Sixth Edition. 2001-05
If the direction of motion is also given, then the velocity of the body is determined; velocity is a vector quantity, having both magnitude and direction, while speed is a scalar quantity, having only magnitude.
Motion at speeds approaching the speed of light must be described by the theory of relativity.
Although a person sitting in a car is at rest with respect to the car, both in motion with respect to the earth, and the earth is in motion with respect to the sun and the center of the galaxy.

 Motion Sickness-Topic Overview
Motion sickness is sometimes called airsickness or seasickness.
Common symptoms of motion sickness are a general sense of not feeling well (malaise), nausea, vomiting, headache, and sweating.
If you can't stop the motion, you may be able to reduce the feeling of queasiness by sitting or lying down in an area that appears to move the least.

 Proper Motion   (Site not responding. Last check: )
Proper motion is usually denoted by the Greek symbol "mu", and is a velocity that is usually quoted in units of seconds of arc per year.
Were it not for the motion of the Earth around the Sun, proper motion would lead to a simple drift of the position of a star on the celestial sphere in a particular direction.
The superposition of these two motions (a straight linear drift from the proper motion and elliptical motion from the parallax effect) then leads to a wavy path of the star on the celestial sphere.

 Motion camouflage
Motion camouflage is a stealth behaviour that allows a predator to conceal its apparent motion on approaching a moving prey.
Motion camouflage was initially inspired by observations of the mating tactics of male hoverlies tracking females (see Srinivasan and Davey, 1995).
If the hoverflies and dragonfly flights are indeed instances of motion camouflage behaviour, it is not clear that the technique itself is being used offensively (though in the case of the hoverfly it may be a precursor to an offensive manoeuvre).

 The Physics Classroom
In Unit 2 of this course, we learned how Newton's laws help to explain the motion (and specifically, the changes in the state of motion) of objects which are either at rest or moving in 1-dimension.
The horizontal motion of the projectile is the result of the tendency of any object in motion to remain in motion at constant velocity.
Due to the absence of horizontal forces, a projectile remains in motion with a constant horizontal velocity; horizontal forces are not required to keep a projectile moving horizontally.

 Stop motion - Encyclopedia.WorldSearch   (Site not responding. Last check: )
More recently, stop motion has been used in the works of Aardman Animation, including the Wallace and Gromit films as well as their film Chicken Run.
Another variation on stop motion is go motion, first used on the film Dragonslayer, which involves moving the model slightly during each exposure to produce a more realistic motion blurring effect.
Nowadays the almost universal use of computer generated imagery has effectively rendered stop motion obsolete as a serious special effects tool, although it is still widely used on children's programming, commercials, and the occasional comic film.

 Visual Element-Motion
In Donis A. Dondis' view, motion, the final visual element, is perhaps "one of the most dominant visual forces in human experience." As she explains in A Primer of Visual Literacy, true motion exists only in the physical world.
Even in motion pictures, however, true movement is only simulated, for filmed or videotaped motion is actually composed of a series of still images, each only slightly different from the previous one.
Our ability to recognize motion in a series of still pictures is the result of a combination of the phenomena known as the "persistance of vision," and the "phi effect." Persistance of vision refers to the phenomenon by which the eye briefly retains the afterimage of the last frame until the next one is visible.

 Motion
In physics, motion means a change in the position of a body with respect to time, as measured by a particular observer in a particular frame of reference.
Until the end of the 19th century, Newton's laws of motion, which he posited as axioms or postulates in his famous Principia, were the basis of what has since become known as classical physics.
It is interesting to note, however, that because motion is defined as the proportion of space to time, these concepts are prior to motion, just as the concept of motion itself is prior to force.

 Description of Motion
Motion is described in terms of displacement (x), time (t), velocity (v), and acceleration (a).
The case of motion in one dimension (one direction) is a good starting point for the description of motion.

Such cosmic concepts of motion are nonetheless hard to grasp intuitively, and so in practice we invariably think of something sitting motionless on the ground as being "at rest" while a car driving over the ground is "in motion".
If the circular motion of the handle is 30 centimeters per revolution, for example, and one turn of the screw lifts a weight by one centimeter, then the mechanical advantage is 30 to 1.
The friction force that resists putting an object in motion is known as "static friction", and the lower friction force that resists keeping an object in motion is known as "sliding friction".

 Physics Demonstrations - Motion
Motion, more properly called "mechanics," is the oldest branch of physics, having been put on a firm quantitative basis by Isaac Newton (1642-1727) who by the age of 24 had also developed calculus, which subsequently became an indispensable tool of science.
The study of motion is often viewed as relatively mundane, but Albert Einstein (1879-1955) at the age of 26, while employed at the Swiss Patent Office, thought deeply about the motion of light and revolutionized our understanding of the relation of space and time.
The study of motion offers the opportunity to develop concepts such as the conservation of energy that are relevant to all branches of physics.

 Macworld: Review: Motion 2
Motion still lacks a true 3-D environment—you can’t set multiple cameras or move objects within 3-D space—but when combined with basic 2-D motion, the Basic 3D filter allows you to simulate many of the 3-D operations and movements that you’d get in a true 3-D compositing program.
Motion 1 had excellent particle filters, and Motion 2 builds on these with dozens of new particle presets that give you a huge assortment of natural and stylized particle effects.
Motion isn’t an After Effects killer, but it can replace After Effects for many motion-graphics and compositing tasks, and it does so with a working environment that is tremendously superior.

A special case of motion analysis is when the camera is actually static with respect to its environment, but other objects are moving.
We may, for instance, assume that the camera motion is reasonably smooth, and use many frames to build up an accurate estimate of the structure and motion.
An alternative way to get information from motion is to assume that the flow in some small region of the image is the result of motion relative to a smooth patch of surface.

 motion - Definitions from Dictionary.com
Motion, move, movement refer to change of position in space.
Motion denotes change of position, either considered apart from, or as a characteristic of, something that moves; usually the former, in which case it is often a somewhat technical or scientific term: perpetual motion.
The chief uses of move are founded upon the idea of moving a piece, in chess or a similar game, for winning the game, and hence the word denotes any change of position, condition, or circumstances for the accomplishment of some end: a shrewd move to win votes.

 The Museum of Unworkable Devices
Perpetual motion machine proposals are often dismissed by scientists in a manner that appears to the layperson as hasty rejection using dogmatic assertions that such machines are prohibited from working by the "laws of thermodynamics".
During any virtual (imagined) motion, it is supplying new mass to the portion of chain lying on one side of the ramp exactly as fast as the portion of chain on the other side of the ramp loses mass.
If an assumed (virtual) motion of the machine results in a final state of the system (the machine and its interactive environment) indistinguishable from its initial state, and zero net work is done on the system during this motion (no work in; no work out) then that assumed motion will not occur.
