The rate of motion of an object is to find out the distance traveled by the object in unit time is referred as speed. ![]() When an object covers equal distance in equal time interval is called uniform motion, whereas when an object covers unequal distance in equal time interval is called non-uniform motion. In short, two different physical quantities – the distance and the displacement are used to describe the overall motion of an object and to locate its final position with reference to its initial position at a given time.Ĭonsider the example of train which moves from station A to station B and comes back from station B to station A, here distance covered by train is from station A to B and then back B to A, but the displacement is zero as train is back to initial junction Magnitude of the displacement for a course of motion may be zero but the corresponding distance covered is not zero. Magnitude of the displacement is not equal to the distance traveled by an object. The shortest distance measured form the initial to the final position of an object is known as the displacement. The numerical value in physical quantity is its magnitude. Motion of the object is described by the numerical value and not the direction of motion. Initial position of an object is described by a specific reference point which is called as origin. Motion may be in a straight line, or in circular path, or rotate or vibrate in nature. ![]() Earth, planets, stars, galaxies, atoms, molecules, blood in the body are all the examples of motion. Send us feedback about these examples.Motion is defined as the change in position of object with time. ![]() These examples are programmatically compiled from various online sources to illustrate current usage of the word 'inertia.' Any opinions expressed in the examples do not represent those of Merriam-Webster or its editors. Philip Ball, Scientific American, See More Jeffrey Sonnenfeld, Fortune, In this case, the fusing plasma is held in place only fleetingly by its own inertia after the experiment triggers fusion by squeezing the fuel abruptly and heating it intensely-a scheme called inertial confinement fusion. Timothy Noah, The New Republic, With no clear playbook, C-suites seem to be muddling through largely along three vastly divergent paths: significant withdrawal, gradual scaling back, and inertia (or even expansion). WIRED, 17 June 2023 As with much of defense spending in the United States, the trouble is some combination of inertia and parochial interests. 2023 Clearly, Reddit is hoping that inertia and customer loyalty keep people on its site. Christopher Flavelle,, 16 July 2023 Job 3 is to counteract the forces of inertia to get people moving from the current to the aspirational state. 2023 The trend could begin to dislodge the inertia that underlies America’s struggle to adapt to climate change: Technologies exist to protect homes against severe weather - but those innovations have been slow to seep into mainstream homebuilding. ![]() 2023 Therefore, drag strength, smooth operation, low start-up inertia, and heat resistance become important. Michael Barnett, Foreign Affairs, 14 Apr. Recent Examples on the Web There are politicians in all camps who want to keep a lid on the conflict, generally not in service of any strategy for resolution but out of a sense of inefficacy and inertia.
