41Trajectory — is the path a moving object follows through space. The object might be a projectile or a satellite, for example. It thus includes the meaning of orbit the path of a planet, an asteroid or a comet as it travels around a central mass. A trajectory… …
42Specific orbital energy — In the gravitational two body problem, the specific orbital energy (or vis viva energy) of two orbiting bodies is the constant sum of their mutual potential energy ( ) and their total kinetic energy ( ), divided by the reduced mass. According to… …
43Concentrated solar power — The PS10 Solar Power Plant concentrates sunlight from a field of heliostats onto a central solar power tower. Concentrated solar power (CSP) systems use mirrors or lenses to concentrate a large area of sunlight, or solar thermal energy, onto a… …
44Elliptic orbit — A small body in space orbits a large one (like a planet around the sun) along an elliptical path, with the large body being located at one of the ellipse foci …
45Polar coordinate system — Points in the polar coordinate system with pole O and polar axis L. In green, the point with radial coordinate 3 and angular coordinate 60 …
46Laplace–Runge–Lenz vector — Throughout this article, vectors and their magnitudes are indicated by boldface and italic type, respectively; for example, left| mathbf{A} ight| = A. In classical mechanics, the Laplace–Runge–Lenz vector (or simply the LRL vector) is a vector… …
47Lorentz group — Group theory Group theory …
48Cartan connection — In the mathematical field of differential geometry, a Cartan connection is a flexible generalization of the notion of an affine connection. It may also be regarded as a specialization of the general concept of a principal connection, in which the …
49Riemann surface — For the Riemann surface of a subring of a field, see Zariski–Riemann space. Riemann surface for the function ƒ(z) = √z. The two horizontal axes represent the real and imaginary parts of z, while the vertical axis represents the real… …
50Universal variable formulation — In orbital mechanics, the universal variable formulation is a method used to solve the two body Kepler problem. It is an improvement on Kepler s Equation, generalizing it to apply not only to elliptic orbits, but also parabolic and hyperbolic… …
