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. Informally, it is the point at which a cutout of the shape could be perfectly balanced on the tip of a pin. 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.

We equivalently represent the system of forces by single force acting at a specific point. The centroid coincides with the center of mass or the center of gravity only if the material of the body is homogenous density or specific weight is constant throughout the body.

## Centre of gravity

Centre of gravity , in physics , an imaginary point in a body of matter where, for convenience in certain calculations, the total weight of the body may be thought to be concentrated.

The center of gravity is a geometric property of any object. The center of gravity is the average location of the weight of an object. We can completely describe the motion of any object through space in terms of the translation of the center of gravity of the object from one place to another, and the rotation of the object about its center of gravity if it is free to rotate. If the object is confined to rotate about some other point, like a hinge, we can still describe its motion. In flight, both airplanes and rockets rotate about their centers of gravity.

Every object is said to weigh a certain amount and have mass. Both mass and weight come into play when you try to balance an object. While balancing, the centre of the object is where the gravitational force is concentrated.

На легком летнем костюме, как и на загорелой коже, не было ни морщинки. Его густые волосы имели натуральный песочный оттенок, а глаза отливали яркой голубизной, которая только усиливалась слегка тонированными контактными линзами. Оглядывая свой роскошно меблированный кабинет, он думал о том, что достиг потолка в структуре АНБ. Его кабинет находился на девятом этаже - в так называемом Коридоре красного дерева. Кабинет номер 9А197.

Беккер безучастно кивнул: - Так мне сказали. Лейтенант вздохнул и сочувственно помотал головой. - Севильское солнце бывает безжалостным.
