1864 Reader 2 Apr. 429/3 Till and about the year 1780..the weightiest authorities inclined towards the kinetic theory of heat.

1866 London Rev. 2 June 615/2 Correct principles of kinetic science.

1870 P. G. Tait in Nature 29 Dec. 163/2 The grand modern ideas of Potential and Kinetic Energy cannot be too soon presented to the student.

1871 Sir W. Thomson in Daily News 3 May The kinetic theory of gases, shadowed forth by Lucretius, definitely stated by Daniel Bernoulli, largely developed by Herapath, made a reality by Joule, and worked out to its present advanced state by Clausius and Maxwell.

1879 W. Thomson & P. G. Tait Treat. Nat. Philos. (new ed.) I: Pt. i. §357 If, from any one configuration, two courses differing infinitely little from one another have again a configuration in common, this second configuration will be called a kinetic focus relatively to the first: or..these two configurations will be called conjugate kinetic foci.

1881 R. L. Stevenson Virginibus Puerisque (ed. 8) 111 I still remember that the spinning of a top is a case of Kinetic Stability.

1891 N.E.D. at Energy Actual, kinetic, or motive energy, i.e. the power of doing work possessed by a moving body by virtue of its motion.

1954 Aircraft Engineering XXVI. 138/3 Kinetic heating is caused by two related phenomena; first the adiabatic compression of the air as it is brought up to the velocity of the leading edge or nose of the body and second the frictional heating which takes place in the boundary layer as the air adjacent to the surface tends to accelerate the air, through which the plane is passing, up to the flying speed.

1959 L. Broglio in Adv. Aeronaut. Sci. I. 216 The design of an aircraft or missile is often ruled by the transient-temperatures of its external surface, due to kinetic heating and radiation.

1970 Progr. Aerospace Sci. XI. 64 Another effect which occurs in flight..concerns the influence of kinetic heating.
