1treated as singular The branch of mechanics concerned with the motion of bodies under the action of forces.

*‘The training allows astronauts to become familiar with the dynamics of body motion under weightless conditions.’**‘Niccolò Tartaglia's early publications on mechanics, dynamics, and motion were in fact the first modern studies of ballistics.’**‘The first volume covered dynamics, mechanics, hydrostatics, hydraulics, aerostatics, and pneumatics.’**‘Newton used Kepler's insights to explore mathematically the dynamics of planetary motion.’**‘Newton's work in calculus was all to work out the dynamics of motion, so there was really no difference.’**‘In 1958 Leimanis published some recent advances in the dynamics of rigid bodies and celestial mechanics.’**‘Molecular mechanics and dynamics use an empirical energy function known as a force field to model the conformation of a molecule.’**‘The main characteristic of all intermittent flight modes is periodic variation in thrust generated by the flapping wings, and therefore in the dynamics of the body.’**‘Only after Galileo had become famous through his discoveries in the area of mechanics, dynamics and optics, did he admit his Copernican position in print.’**‘Also, I do teach Nik's principles of space time, shape, motion, dynamics - and I add a few of my own things.’**‘In some cases we now have enough understanding of the molecular mechanisms to capture their dynamics into mathematical models.’**‘This gives it a stiffer body shell and better dynamics.’**‘Euler here also begins developing the kinematics and dynamics of rigid bodies, introducing in part the differential equations for their motion.’**‘These solutions show that the dynamics of motion is dramatically slowed down if one end of a microtubule is fixed instead of free.’**‘We begin with a qualitative picture of the dynamics of lipid motions given in Figs.7 and 8.’**‘Reared as fliers, they had an instinctive grasp of the dynamics of three-dimensional motion.’**‘A year later he obtained the first solution for the problem of the dynamics of colliding elastic bodies.’**‘Huygens attempts for the first time in this work to study the dynamics of bodies rather than particles.’**‘The experiments covered computational and thermal structures, structural mechanics and dynamics.’**‘These scientific giants had accurately described phenomena of dynamics and celestial mechanics, but neither had formulated scientific explanations.’*

- 1.1usually with modifier The branch of any science in which forces or changes are considered.
*‘chemical dynamics’**‘Events of DNA duplication were described in many eukaryote genomes, but are the duplication dynamics similar in all eukaryotes?’**‘Do polyps of other cnidarian species have a tissue dynamics similar to that of hydra?’**‘At Haverford College, I generally include an introduction to fluid dynamics in our undergraduate mechanics course.’**‘The problem is, because of fluid dynamics, when the body is moving, the vestibular system generates erroneous cues about our orientation.’**‘They are performing research in such advanced fields as computational fluid dynamics, electromagnetics, power electronics and composite materials.’**‘Former Olympic bronze medal winner Wieger Mensonides studied mechanical engineering and uses his knowledge of fluid dynamics to prime the Dutch champion's technique.’**‘To these defenders I mention the handling of pieces of art, foodstuffs, beverages, and host of other things involving mechanical dynamics.’**‘Sysmex has developed a new methodology of cell growth dynamics based on C2P by using a proprietary chip-based multi-protein analysis.’**‘These populations offer a unique opportunity to monitor evolutionary dynamics in ancestral populations that harbor multiple strains of Wolbachia.’**‘The ratios of branch lengths provided a starting point to further probe the evolutionary dynamics at Chs and Adh by testing for correlations between the ij matrices.’**‘Here, we use salamander pheromone delivery as a test case for dissecting the evolutionary dynamics at multiple levels in a functional complex.’**‘This capacity may result in substantially different population and evolutionary dynamics than in organisms incapable of withdrawing from ongoing stress.’**‘In pursuing our overall goal of a better characterization of the evolutionary dynamics at the molecular level, we had several objectives.’**‘Glycophorins, however, have a rather different evolutionary dynamics than the immunoglobulins.’*

2The forces or properties which stimulate growth, development, or change within a system or process.

*‘the dynamics of changing social relations’**‘Economic development creates its own dynamics and tensions in the social and political spheres, which must be addressed.’**‘As this history makes clear, a powerful set of internal dynamics drove the development of the European economy in the second half of the twentieth century.’**‘The question is: given the current political dynamics and developments inside the party, what will happen now?’**‘This is because these votes may well change the political dynamics within the conservative and liberal movements.’**‘Social formations and political institutions are examined as they operate within their own dynamics as well as in relation to Europe and world capitalism.’**‘By the Heisenberg principle, their participation has changed the dynamics and interests in the election process.’**‘Hopefully, though, in the pages that follow I can shine some light on the dynamics at work in this crazy software development universe which we are lucky enough to call home.’**‘Heal's many drawings show his devotion to this process, devising groupings to allow specific contrasts or emotional dynamics between works to emerge.’**‘After speaking to the brothers Moffatt, you can really sense their distinct personalities and the dynamics between them.’**‘We are all implicated in the social and cultural dynamics her work contests.’**‘Clearly in many situations there are dynamics that hold people together that outsiders are just not privy to.’**‘The competitive dynamics among siblings can have a profound effect on their growth and survival and, thereby, also on parental fitness.’**‘Marx sharpened and deepened this concept, and then used it to explore capitalism's class relations and internal dynamics.’**‘Listening to a sit-down debate changes the dynamics so I'm curious to hear what people thought.’**‘Electoral politics are ultimately an expression of underlying cultural dynamics.’**‘The setup is rather mechanical, but the dynamics of the relationship between Anna and William are sensitively explored.’**‘And I fear that this result will set in motion dangerous dynamics that even the relatively young among us will be wrestling with and contending with for the rest of our lives.’**‘The Fed ease that triggers the refinancing surge sets into motion the cumulative dynamics of an economic expansion.’**‘Changes in money supply set in motion new dynamics that give rise to changes in demands for goods and to changes in their relative prices.’**‘Once prices start falling it is held that this can set in motion very dangerous dynamics, which can lead to a severe economic slump.’*

3Music

The varying levels of volume of sound in different parts of a musical performance.*‘Variety can also be obtained without affecting the musical substance simply by repeating a melody with different dynamics or instruments.’**‘A flute just always sounds flutey, no matter how exquisitely it is phrased, or how cleverly the flautist manages the dynamics.’**‘Unless the conductor and the orchestra have a disciplined sense of dynamics when accompanying singers, we wind up believing we're not meeting expectations.’**‘The Petrarchian Sonnet is not quite as successful, Cliburn's dynamics favoring mezzo-forte and forte a little too much throughout.’**‘The piano projected brightly, the themes warmly shaped and the passagework bristling and with sensitive dynamics.’*
