  2. Rectilinear - Wikipedia

    en.wikipedia.org/wiki/Rectilinear

    Rectilinear prophecy, where a straight line can be drawn from the prophecy to the fulfillment without any branches as in the case of typological interpretations Near-rectilinear halo orbit , a highly-elliptical orbit around a Lagrangian point of a moon, that due to the moons orbital movement, will be nearly rectilinear in some frames of reference.

  3. Linear motion - Wikipedia

    en.wikipedia.org/wiki/Linear_motion

    Linear motion, also called rectilinear motion, [1] is one-dimensional motion along a straight line, and can therefore be described mathematically using only one spatial dimension. The linear motion can be of two types: uniform linear motion , with constant velocity (zero acceleration ); and non-uniform linear motion , with variable velocity ...

  4. Rectilinear propagation - Wikipedia

    en.wikipedia.org/wiki/Rectilinear_propagation

    Rectilinear propagation was discovered by Pierre de Fermat. [1] Rectilinear propagation is only an approximation. [citation needed] The rectilinear approximation is only valid for short distances, in reality light is a wave and have a tendency to spread out over time. The distances for which the approximation is valid depends on the wavelength ...

  5. Motion - Wikipedia

    en.wikipedia.org/wiki/Motion

    It produces very accurate results within these domains and is one of the oldest and largest scientific descriptions in science, engineering, and technology. Classical mechanics is fundamentally based on Newton's laws of motion. These laws describe the relationship between the forces acting on a body and the motion of that body.

  6. Scientific terminology - Wikipedia

    en.wikipedia.org/wiki/Scientific_terminology

    Scientific terminology is the part of the language that is used by scientists in the context of their professional activities. While studying nature, scientists often encounter or create new material or immaterial objects and concepts and are compelled to name them.

  7. Kinematics - Wikipedia

    en.wikipedia.org/wiki/Kinematics

    Kinematics is a subfield of physics and mathematics, developed in classical mechanics, that describes the motion of points, bodies (objects), and systems of bodies (groups of objects) without considering the forces that cause them to move.

  8. Inertial frame of reference - Wikipedia

    en.wikipedia.org/wiki/Inertial_frame_of_reference

    A reference frame in which a mass point thrown from the same point in three different (non co-planar) directions follows rectilinear paths each time it is thrown, is called an inertial frame. [13] The inadequacy of the notion of "absolute space" in Newtonian mechanics is spelled out by Blagojevich: [14]

  9. Polygon - Wikipedia

    en.wikipedia.org/wiki/Polygon

    A skew polygon does not lie in a flat plane, but zigzags in three (or more) dimensions. The Petrie polygons of the regular polytopes are well known examples. An apeirogon is an infinite sequence of sides and angles, which is not closed but has no ends because it extends indefinitely in both directions.
