Motion

change in position of an object over time; a body is said to be in motion if it changes its position or orientation with respect to its immediate surroundings
(Redirected from Mobility)

Motion, in physical terms, refers to changes of position of an object with respect to time and some spacial reference points, typically observed and described by measures of displacement, direction, velocity, acceleration, as well as general regions of time and spatial locality. The term can also signify a continuous changes in the configurations of a physical system involving waves or quantum particles and the probabilities of these occupying specific positions. It is also used to refer to formal political procedures of legislative motions, including parliamentary motions, as well as legal motions. Move and Movement are related words for either initiating or sustaining any of these types of physical or formal "motion", but which is also used in reference to influences upon emotional states as well.

Every body continues in its state of rest, or of uniform motion in a right line, unless it is compelled to change that state by forces impressed upon it. ~ Isaac Newton

  • Intuition is the wisdom formed by feeling and instinct - a gift of knowing without reasoning... Belief is ignited by hope and supported by facts and evidence - it builds alignment and creates confidence. Belief is what sets energy in motion and creates the success that breeds more success.
  • There are as many types of motion or change as there are meanings of the word 'is'.
  • The fulfilment of what exists potentially, in so far as it exists potentially, is motion.
  • In a race, the quickest runner can never overtake the slowest, since the pursuer must first reach the point whence the pursued started, so that the slower must always hold a lead.
  • If everything when it occupies an equal space is at rest, and if that which is in locomotion is always occupying such a space at any moment, the flying arrow is therefore motionless.
  • Nicholas of Cusa... dared to teach that there is nothing at all without motion in the universe — the latter is infinite in all directions, possessing no centre — and that the earth travels its course in common with the other stars. That this widening of the intellectual horizon of the age, with the suggestion of new centres of interest, was a decisive factor in Copernicus' personal development, the brief biographical sketch which he gives of himself in the De Revolutionibus strongly suggests.
  • It is in the admission of ignorance and the admission of uncertainty that there is a hope for the continuous motion of human beings in some direction that doesn't get confined, permanently blocked, as it has so many times before in various periods in the history of man.
  • Movement through space is fundamental to life: movement of the entire organism, such as walking; movement of a part of the organism, such as an arm; movement of materials within the organism, such as food in the stomach; movement of offspring into the external world, as in birth. Each is a mechanism indispensable to virtually all members of the animal kingdom. In the end, it is muscle that accomplishes movement. As a consequence, muscle is the most abundant tissue in most animals and accounts for much of the energy-consuming cellular work in an active animal.

  • Yet it is in this loneliness that the deepest activities begin. It is here that you discover act without motion, labor that is profound repose, vision in obscurity, and, beyond all desire, a fulfillment whose limits extend to infinity.
  • The connection to place, to the land, the wind, the sun, stars, the moon... it sounds romantic, but it's true - the visceral experience of motion, of moving through time on some amazing machine - a few cars touch on it, but not too many compared to motorcycles. I always felt that any motorcycle journey was special.
  • Look at what you want to change, gather a few people who believe in it like you do, and start moving forward. It's important to remember that you don't always need a destination. Sometimes, you just have to make forward motion. And you absolutely can.

  • Painting is concerned with all the 10 attributes of sight; which are: Darkness, Light, Solidity and Colour, Form and Position, Distance and Propinquity, Motion and Rest.
  • One purpose of physics is to study the motion of objects—how fast they move, for example, and how far they move in a given amount of time. NASCAR engineers are fanatical about this aspect of physics as they determine the performance of their cars before and during a race. Geologists use this physics to measure tectonic-plate motion as they attempt to predict earthquakes. Medical researchers need this physics to map the blood flow through a patient when diagnosing a partially closed artery, and motorists use it to determine how they might slow sufficiently when their radar detector sounds a warning.
