The magnitude of the radial acceleration is given by the expression vi/BC, v being the velocity of the point B about the point C. This velocity can always be found from the velocity diagram of the chain of which the link forms a part. If u be the acceleration at unit distance, the equation of motion becomes the solution of which may be written in either of the forms x=A cos et+B sin ut, x=a cos (rt+~), (6). Example Sentences for "accelerate" The acceleration in this car is amazing: 0 - 60 in just over 3 seconds!Harvey accelerated through the intersection as the light turned yellowThe progress of the disease seems to have accelerated somewhat in the last week, and his doctor is very worried. 219. kinematics of a particle in a plane including the case when velocity or acceleration depends on time (but excluding use of acceleration. Login or get an account. Again, the velocity parallel to the normal at P changes from o to vi,l, ultimately, so that the normal acceleration is vd~,&/dt. This represents about two-thirds of the total variation of Galileo's acceleration between the equator and the poles, the balance being due to the ellipticity of the figure of the earth. As a law of acceleration of the planets relatively to the sun, its approximate agreement with Kepler's third law of planetary motion follows readily from a consideration of the character of the acceleration of a point moving uniformly in a circle. Definition of Acceleration an escalation in pace or speed Examples of Acceleration in a sentence With a little acceleration on my part, I should be able to catch up with the mailman’s truck. (ga 2 /2b); or if the height of the centre of gravity of a column like a gravestone above the base on which it rests is y, and x is the horizontal distance of this centre from the edge over which it has turned, then the acceleration or suddenness of motion which caused its overthrow is measured, as pointed out by C. D. Atwood's published works, exclusive of papers contributed to the Philosophical Transactions, for one of which he obtained the Copley medal, are as follows: - Analysis of a Course of Lectures on the Principles of Natural Philosophy (Cambridge, 1784); Treatise on the Rectilinear Motion and Rotation of Bodies (Cambridge, 1784), which gives some interesting experiments, by means of which mechanical truths can be ocularly exhibited and demonstrated, and describes the machine, since called by Atwood's name, for verifying experimentally the laws of simple acceleration of motion; Review of the Statutes and Ordinances of Assize which have been established in England from the 4th year of King John, 1202, to the 37th of his present Majesty (London, 1801), a work of some historical research; Dissertation on the Construction and Properties of Arches (London, 1801), with supplement, pt. Will you need a car with great acceleration and performance? Instead of the operation of superposing accelerations, we may compound the several forces acting on a particle by the parallelogram law (see Mechanics) into what may be called the resultant force, the total acceleration of the particle being the same as if this alone acted. Random good picture Not show. The most fuel efficient driving requires slow and steady acceleration. Examples, completely worked out, of velocity and acceleration diagrams for the slider crank chain, the four-bar chain, and the mechanism of the Joy valve gear will be found in ch. , (7) and when q is stationary, the acceleration is normal to the surface H = constant, and the stream line is a geodesic. Let e denote the quantity by which the energy exerted in each cycle of the working of the machine alternately exceeds and falls short of the work performed, and which has consequently to be alternately stored by acceleration and restored by retardation of the flywheel. Acceleration to 60 mph takes a mere 5.7 seconds. Since high average speed on a line with frequent stops depends largely on rapidity of acceleration, the tendency in modern equipment is to secure as great an output of power as possible during the accelerating period, with corresponding increase in weight available for adhesion. If we're going to make the play, my husband must press down on the gas and accelerate the vehicle. A naive acceleration run was also setup with too little run off forcing the car skid off to the grass verge. If dw/dt is the angular acceleration of the link, dw/dt X CB is the tangential acceleration of the point B about the point C. Generally this tangential acceleration is unknown in magnitude, and it becomes part of the problem to find it. armature coils and a commutator, its inertia is small, allowing rapid acceleration and deceleration. Feel the surge of acceleration. Acceleration-clause definitions A clause in a loan agreement that can be invoked by the lender when the borrower fails to make payments, files bankruptcy, or otherwise breaks a loan agreement. The above law of gradual evolution is perfectly consistent with a second principle, namely, that at certain times evolution is much more rapid than at others, and that organisms are accelerated or retarded in development in a manner broadly analogous to the acceleration or retardation of separate organs. Among his most remarkable works may be mentioned his ten memoirs on quantics, commenced in 1854 and completed in 1878; his creation of the theory of matrices; his researches on the theory of groups; his memoir on abstract geometry, a subject which he created; his introduction into geometry of the "absolute"; his researches on the higher singularities of curves and surfaces; the classification of cubic curves; additions to the theories of rational transformation and correspondence; the theory of the twenty-seven lines that lie on a cubic surface; the theory of elliptic functions; the attraction of ellipsoids; the British Association Reports, 1857 and 1862, on recent progress in general and special theoretical dynamics, and on the secular acceleration of the moon's mean motion. As notable instances may be mentioned Laplace's discoveries relating to the velocity of sound and the secular acceleration of the moon, both of which were led close up to by Lagrange's analytical demonstrations. Among the many difficulties which beset the question, not the least obvious was the length of time during which the Church must remain without a ruler, if - as Sigismund and the German nation demanded - the papal election were deferred till the completion of the internal reforms. Acceleration in a sentence | acceleration example sentences. These features are formed as a result of particle acceleration in the hairpin field structure of the distant tail. acceleration definition is - the act or process of moving faster or happening more quickly : the act or process of accelerating. oxytocin induction or acceleration, and prostaglandin E2 gel induction. He attained correct views as to the character of centrifugal force in connexion with Galileo's theory; and, when the fact of the variation of gravity (Galileo's acceleration) in different latitudes first became known from the results of pendulum experiments, he at once perceived the possibility of connecting such a variation with the fact of the earth's diurnal rotation relatively to the stars. Meaning: ['diː‚selə'reɪʃn] n. 1. a decrease in rate of change 2. To find the angular acceleration A, draw kI, bt respectively parallel to and at right angles to the link KB. The unit of acceleration is the acceleration of a point which gains unit velocity in unit time; it is accordingly denoted by LT2. this is a result of the responding and manipulated variables. Copyright © 2016 sentencedict.com All Rights Reserved Contact. It has since been discovered, however, that the magnitude of the acceleration in question is not exactly the same at different places on the earth, the range of variation amounting to about 2%. In applying this principle to the drawing of an acceleration diagram for a mechanism, the velocity diagram of the mechanism must be first drawn in order to afford the means of calculating the several radial accelerations of the links. The term "weight" denotes a magnitude of the same nature as a force; the weight of a body is the product of the mass of the body by the acceleration of gravity; in particular, the normal weight of a body is the product of the mass of the body by the normal acceleration of gravity. The year 1787 was rendered further memorable by Laplace's announcement on the 19th of November (Memoirs, 1786), of the dependence of lunar acceleration upon the secular changes in the eccentricity of the earth's orbit. ); and it appears that the velocity of the point V along the hodograph represents in magnitude and in directon tbt acceleration in the original orbit. acceleration of electrons by Langmuir waves which are excited by the pump wave. Acceleration definition is - the act or process of moving faster or happening more quickly : the act or process of accelerating. It is legal for the bank to make this demand in most states because mortgages contain "acceleration clauses.". The semicircular canals of the inner ear sense changes in angular acceleration. The rapid variation of certain groups of animals or the acceleration of certain organs is also not evidence of the sudden appearance of new adaptive characters. The methods of the two preceding sections may be used when the acceleration of two points in the rod are known. Examples of 'acceleration' in a sentence acceleration. Phil.

When a machine undergoes alternate acceleration and retardation, so that at certain instants of time, occurring at the end of intervals called periods or cycles, it returns to its original speed, then in each of those periods or cycles the alternate excesses of energy and of work neutralize each other; and at the end of each cycle the principle of the equality of energy and work stated in 87, with all, its consequences, is verified exactly as in the case of machines of uniform speed. There's a strong correlation between acceleration and jumping ability, so make it a point to include sprinting drills into your routine regularly. To reduce the hardware acceleration: Open the Control Panel. The only way you can actually calculate the acceleration of the trolley is by using a ticker timer. The average date of the break-up is April 11 th at Tver, and 14 days later about Kostroma, from which point a regular acceleration is observed (April 16th at Kazan, April 7th at Tsaritsyn, and March 17th at Astrakhan). (6) On a curved bridge the centrifugal load due to the radical acceleration of the train. These considerations also indicate what a difficult matter it is to find the exact rate of working against the resistances, because of the difficulty of securing conditions which eliminate the effect both of the gradient and of acceleration. A small body hanging by a string, at rest relatively to the earth, moves relatively to this base uniformly in a circle; that is to say, with constant acceleration directed towards the earth's axis. As an example, consider the equation for the velocity v of an object that undergoes an acceleration a for a time t. Hydrostatic equation: An equation expressing the vertical pressure forces in balance with the gravitational acceleration. Copyright © 2020 LoveToKnow. (physics) a rate of decrease in velocity 3. the act of decelerating; decreasing the speed. mately, and the tangential acceleration at P is therefore dv/dt or 1. Another downgraded the single-engine plane’s acceleration rates and ability to turn. In the case of a constant force, the acceleration or x is, according to (1), constant, and we have say, the general solution of which is x=1/8ati+At+B. - The New Adventures of Old Tom. Sentence Examples. How to use acceleration in a sentence. As in " Study No. How to use acceleration in a sentence Looking for sentences and phrases with the word acceleration? According to Galileo's concept of gravitation, a dropped stone falls with constant acceleration down towards the Earth. How to say acceleration in English? of Jupiter and Saturn in 1784, and of the " secular acceleration " of the moon in 1787. Motion is obtained from a continuous-current generator driven by an alternating motor with a very heavy fly-wheel, a combination known as the Ilgner transformer, which runs continuously with a constant draught on the generating station, the extremely variable demand of the winding engine during the acceleration period being met by the energy stored in the fly-wheel, which runs at a very high speed. Meaning, pronunciation, picture, example sentences, grammar, usage notes, synonyms and more. convergence acceleration, Incomplete gamma Function. The acceleration therefore remains the same, and the velocity is unaltered.

The acceleration therefore remains the same, and the velocity is unaltered. When the link forms part of a mechanism the respective accelerations of two points in the link can be determined by means of the velocity and acceleration diagrams described in 82, it being understood that the motion of one link in the mechanism is prescribed, for instance, in the steam-engines mechanism that the crank shall revolve uniformly. where P, as before, denotes the acceleration towards 0. The rate of acceleration will be dv/dt = const. Acceleration and braking aren't complicated at all, as they shouldn't be. The acceleration in this car is amazing: 0 - 60 in just over 3 seconds! kinematics of a particle in a plane including the case when velocity or acceleration depends on time (but excluding use of acceleration. Examples of acceleration in a sentence, how to use it. In addition to the foregoing list, various special locomotive types have been developed for suburban service, where high rates of acceleration and frequent stops are required. This testing allows for rapid acceleration of TCE induced failures. - LAW OF Acceleration And Retardation Illustrated In The Evolution Of The Hind Feet Of The Horse. The number adopted for the value of the normal acceleration of gravity is 980.965 cm/sec-squared. The word usage examples above have been gathered from various sources to reflect current and historial usage. They are carried across the disk by the sun's rotation, partaking in the equatorial acceleration; they also show marked displacements of their own, whether with, or relative to, the neighbouring photosphere does not appear; at the beginning of their life they usually outrun the average daily rotation appropriate to their latitude. To determine the component acceleration of a particle, suppose F to denote any function of x, y, z, t, and investigate the time rate of F for a moving particle; denoting the change by DF/dt, DF = 1t F(x+uSt, y+vIt, z+wSt, t+St) - F(x, y, z, t) dt at = d + u dx +v dy+ w dz and D/dt is called particle differentiation, because it follows the rate of change of a particle as it leaves the point x, y, z; but dF/dt, dF/dx, dF/dy, dF/dz (2) represent the rate of change of F at the time t, at the point, x, y, z, fixed in space. An object's average acceleration over a period of time is its change in velocity (\ Delta \ mathbf { v }) divided by the duration of the period (\ Delta t). From about 1880 the prevailing temper had changed; within a decade of this date the change had become great; since then the influence of Old Testament criticism has grown with increased acceleration. Professor Hemmingwell and Barret, both in space suits, were seated on acceleration couches. The company also says that wear and tear on the gas pedal is the most likely cause of the acceleration problem. This acceleration is denoted by g; its value at Greenwich is about 981 centimetre-second units, or 322 feet per second. acceleration of a particle moving in a circle. Galileo proceeded to measure the motion of a body on a smooth, fixed, inclined plane, and found that the law of constant acceleration along the line of slope of the plane still held, the acceleration decreasing in magnitude as the angle of inclination was reduced; and he inferred that a body, moving on a smooth horizontal plane, would move with uniform velocity in a straight line if the resistance of the air, and friction due to contact with the plane, could be eliminated. " whistler mode chorus associated with electron acceleration to relativistic energies. Rate at which work is done against acceleration. 125) have plane motion and the acceleration of any point C be given in magnitude and direction, the acceleration of any c other point B is the vector sum of X, the acceleration of C, the radial n acceleration of B about C and the A. There were no DirectX video standards, no surround sound, and certainly no 3D acceleration. Derive the velocity profile for optimum, 24. The impetus which the indirect process and the acceleration of civilization in the 15th and 16th centuries gave to the iron industry was so great that the demands of the iron masters for fuel made serious inroads on the forests, and in 1558 an act of Queen Elizabeth's forbade the cutting of timber in certain parts of the country for iron-making. This gives the acceleration of m as modified by the inertia of the wheel. Traducir acceleration de Inglés a español. Sentence Examples.
