constant motion
51Ship motion test — traight line testThe velocity dependent derivatives Yv and Nv of the ship at any draft and trim can be determined from the model test carried in towing tank. The model is towed with a constant velocity corresponding to a given ship Froude no. at… …
52Curve of constant width — A Reuleaux triangle is a curve of constant width. The sides of the square are supporting lines: each touches the curve but does not intersect the interior. The Reuleaux triangle can be rotated whilst always touching each side of the square in a… …
53Laws of motion — Law Law (l[add]), n. [OE. lawe, laghe, AS. lagu, from the root of E. lie: akin to OS. lag, Icel. l[ o]g, Sw. lag, Dan. lov; cf. L. lex, E. legal. A law is that which is laid, set, or fixed; like statute, fr. L. statuere to make to stand. See… …
54Linear motion — is motion along a straight whiteline, and can therefore be described mathematically using only one spatial dimension. It can be uniform, that is, with constant speed, or non uniform, that is, with a variable speed. The motion of a particle (a… …
55Gaussian gravitational constant — Carl Friedrich Gauss expressed the gravitational constant in units of the solar system rather than SI units. The benefit is that the motion of the planets can be accurately described, without exact knowledge of the scale of the solar system or… …
56Brownian motion — This article is about the physical phenomenon; for the stochastic process, see Wiener process. For the sports team, see Brownian Motion (Ultimate). For the mobility model, see Random walk. Brownian motion (named after the botanist Robert Brown)… …
57Gravitational constant — The gravitational constant G is a key quantity in Newton s law of universal gravitation. The gravitational constant, denoted G, is an empirical physical constant involved in the calculation of the gravitational attraction between objects with… …
58Perpetual motion — For other uses, see Perpetual motion (disambiguation). Robert Fludd s 1618 water screw perpetual motion machine from a 1660 wood engraving. This device is widely credited as the first recorded attempt to describe such a device in order to produce …
59Centrifugal force (planar motion) — In classical mechanics, centrifugal force (from Latin centrum center and fugere to flee ) is one of the three so called inertial forces or fictitious forces that enter the equations of motion when Newton s laws are formulated in a non inertial… …
60Boltzmann constant — For the constant pertaining to energy of black body radiation see Stefan–Boltzmann constant Values of k[1] Units 1.3806488(13)×10−23 J K−1 8.617332 …
