The center of mass of an object of uniform density WordNet 3.0
In mathematics and physics, the centroid or geometric center of a plane figure is the arithmetic mean position of all the points in the figure. Wikipedia
Mean position of all the points in the shape; mean position of all the points in all of the coordinate directions; point at which a cutout of the shape could be perfectly balanced on the tip of a pin Wikidata
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. Wiktionary
