Accelerate

Accelerate refers to the change in velocity of an object over time and is central to descriptions of motion in Isaac Newton's Philosophiæ Naturalis Principia Mathematica, Galileo Galilei's kinematic studies, and modern analyses used by institutions such as CERN, NASA, ESA, JAXA, and Roscosmos. The concept underpins technologies developed at laboratories like MIT, Caltech, Stanford University, and Lawrence Berkeley National Laboratory, and it appears in applications ranging from the Wright brothers' first flights to particle experiments at the Large Hadron Collider and propulsion research at SpaceX and Blue Origin.

Etymology

The term originates from the Old French and Latin roots that yielded words used by scholars like Aristotle and Ptolemy in translations preserved in the libraries of Alexandria and later systematized during the work of Johannes Kepler and Galileo Galilei. Renaissance treatises circulated through centers such as Florence, Venice, and Oxford University helped transform the vocabulary used by René Descartes and Christiaan Huygens, influencing later nomenclature in textbooks produced by publishers like Cambridge University Press, Oxford University Press, and Springer Science+Business Media.

Definitions follow formulations given by Isaac Newton and elaborated by Leonhard Euler and Joseph-Louis Lagrange. In classical mechanics it is defined as the derivative of velocity with respect to time as used in the equations derived by Newton in dialogue with contemporaries such as Robert Hooke and Edmond Halley. In relativistic contexts described by Albert Einstein and applied in research at Princeton University and University of Chicago, acceleration relates to four-acceleration in Special relativity and to geodesic deviation in General relativity. In continuum mechanics and fluid dynamics studied by Ludwig Prandtl and Andrey Kolmogorov, acceleration fields appear in the Navier–Stokes formulations used by teams at Imperial College London and ETH Zurich.

Early qualitative accounts appear in treatises by Aristotle and observational chronicles from Tycho Brahe and Nicolaus Copernicus. Quantitative advances emerged through experiments by Galileo Galilei on inclined planes, syntheses by Isaac Newton in the 17th century, and mathematical formalisms by Gottfried Wilhelm Leibniz and Leonhard Euler. The 19th century saw extensions by James Clerk Maxwell and Hermann von Helmholtz influencing industrial research at institutions like Siemens and General Electric. Twentieth-century developments by Albert Einstein, Max Planck, Werner Heisenberg, and Paul Dirac integrated acceleration into relativistic and quantum frameworks used at CERN and national laboratories such as Los Alamos National Laboratory and Oak Ridge National Laboratory.

Acceleration is central to orbital mechanics used by Kepler's laws in missions of NASA's Apollo program, Sputnik launches by Soviet Union agencies, and contemporary missions by ESA and JAXA. It governs vehicle safety systems developed by engineering groups at Toyota, Ford Motor Company, General Motors, and BMW, and appears in biomechanics research at Harvard University and University of Cambridge for studies on human tolerance in Roller coasters and aviation tested by Boeing and Airbus. In sports science explored at FIFA and International Olympic Committee laboratories, acceleration metrics inform training at clubs like Manchester United and FC Barcelona. In materials research, shock and acceleration studies are conducted at facilities such as Sandia National Laboratories and Lawrence Livermore National Laboratory for defense and industrial applications.

The SI unit for acceleration is the metre per second squared (m/s^2), standardized by organizations like the International Bureau of Weights and Measures and codified in documents by International Organization for Standardization. Other units include the foot per second squared used in standards by ASTM International and g-force, defined relative to standard gravity g0 as used in aerospace testing at NASA Ames Research Center and by manufacturers like Lockheed Martin and Northrop Grumman. Measurement techniques employ accelerometers based on piezoelectric crystals utilized by companies like STMicroelectronics and Bosch, MEMS sensors developed at Texas Instruments and Analog Devices, and laser interferometry methods advanced at LIGO and National Institute of Standards and Technology.

Classical models derive from Isaac Newton's second law and Lagrangian and Hamiltonian formalisms advanced by Joseph-Louis Lagrange and William Rowan Hamilton, used in simulations at Sandia National Laboratories and Argonne National Laboratory. Relativistic formulations follow Albert Einstein's field equations and four-vector analysis used in research at Perimeter Institute and CERN. Statistical and stochastic treatments developed by Norbert Wiener and Andrey Kolmogorov inform models in turbulence research at Princeton University and Caltech. Computational approaches employ finite element methods popularized by work at Delft University of Technology and multibody dynamics implemented by software companies such as ANSYS and Dassault Systèmes.
