Crossword clues for centroid
The Collaborative International Dictionary
Centroid \Cen"troid\ (s[e^]n"troid), n. [L. centrum + -oid.] The center of mass, inertia, or gravity of a body or system of bodies.
Wiktionary
n. (context mathematics physics English) The point at the centre of any shape, sometimes called centre of area or centre of volume. For a triangle, the centroid is the point at which the medians intersect. The co-ordinates of the centroid are the average (arithmetic mean) of the co-ordinates of all the points of the shape. For a shape of uniform density, the centroid coincides with the centre of mass which is also the centre of gravity in a uniform gravitational field.

n. the center of mass of an object of uniform density
Wikipedia
In mathematics and physics, the centroid or geometric center of a plane figure is the arithmetic mean ("average") position of all the points in the shape. The definition extends to any object in n- dimensional space: its centroid is the mean position of all the points in all of the coordinate directions. Informally, it is the point at which an infinitesimally thin cutout of the shape could be perfectly balanced on the tip of a pin (assuming uniform density and a uniform gravitational field).
While in geometry the term "barycenter" is a synonym for "centroid", in astrophysics and astronomy, barycenter is the center of mass of two or more bodies which are orbiting each other. In physics, the center of mass is the arithmetic mean of all points weighted by the local density or specific weight. If a physical object has uniform density, then its center of mass is the same as the centroid of its shape.
In geography, the centroid of a radial projection of a region of the Earth's surface to sea level is known as the region's geographical center.
Usage examples of "centroid".
Nuel,” Flaster continued, “you certainly cannot have ‘left’ your centroid anywhere, I believe if you check you’ll find it somewhere near your navel.
Flaster,” Dennis ventured, “since you bring up the subject, I’m sure we’re all interested in the centroid of that vicious little varmint that buzzed the party.
That is, that the orthocenter, centroid, and circumcenter of any triangle must lie in a straight line, with the centroid exactly twice as far from the orthocenter as from the circumcenter.
Glanton's eyes in their dark sockets were burning centroids of murder and he and his haggard riders stared balefully at the kid as if he were no part of them for all they were so like in wretchedness of circumstance.
