Center (American English) or centre (Commonwealth English) has a number of meanings. In geometry, a point that is well-distant from the boundaries of a figure. For instance, for a circle, the center is defined as the point equidistant from all points on the circle's boundary. Similar definitions can be made for other shapes in various geometries, though for arbitrary complex shapes there may be several definitions considered appropriate in some circumstances. See also cente ...

The center of mass of a long, uniform beam (of rectangular or circular cross section) is always at the center of the beam. In locations where Earth's gravity dominates, the center of gravity of a vertical, long, uniform beam is closer to Earth than the center of the beam (although it is still inside the beam). In locations where Earth's gravity dominates, the center of gravity of a horizontal, long, uniform beam is further away from Earth than the center of the beam. (The CG may be outside the beam, if the beam is long enough a ...

The term center is used in various contexts in abstract algebra to denote the set of all those elements that commute with all other elements. More specifically: The center of a group G consists of all those elements x in G such that xg = gx for all g in G. This is a normal subgroup of G. The center of a ring R is the subset of R consisting of all those elements x of R such that xr = rx for all r

A center fielder, abbreviated CF, is the outfielder in baseball who plays defense in center field - the baseball fielding position between left field and right field (e.g., "Mickey Mantle was a center fielder"). In the numbering system used to record defensive plays, the center fielder is assigned the number 8. Outfielders must cover large distances, so speed, instincts and quickness to react to the ball is key. They must be able to catch fly balls above their head and on the run. They must be able to throw the ba ...

In physics, the center of gravity (CG) of an object is a point at which the object's mass can be assumed, for many purposes, to be concentrated. For example, if you hang an object from a string, the object's center of gravity will be directly below the string. The path of an object in orbit depends only on its center of gravity. In objects that are radially symmetric, both the center of gravity and the center of mass coincide. The center of gravity of an object is the average location of its weight. In a uniform gravitation ...

The center frequency f0 (resonant frequency) is the geometric mean between the lower cutoff frequency f1 and the upper cutoff frequency f2 of a frequency band. See also: Band-pass filter. f2 - f1 is called the bandwidth B. Only if the bandwidth f2 - f1 is very small in comparison to the center frequency it is sometimes possible to use this arithmetic mean for calculations, but th ...

The center of mass of an object is a point at which the object's mass can be assumed, for many purposes, to be concentrated. Center of mass - Example. For example, an object can balance on a point only if its center of mass is directly above the point.

The Center of Percussion, or sweet spot, of a sword is the point on the blade where cutting is most effective. It is also the division between the weak and middle sections of the blade. Like any solid object, a sword vibrates when impacted (such as during cutting). In a sword, such vibrational waves are typically almost imperceptible. Every wave expressed by a solid object has rotational nodes where the wave reverses at either end of the object. On a properly-balanced sword, one node is in the tang of the sword (i ...
