The act of curving, or the state of being bent or curved; a curving or bending, normal or abnormal, as of a line or surface from a rectilinear direction; a bend; a curve.

The amount of degree of bending of a mathematical curve, or the tendency at any point to depart from a tangent drawn to the curve at that point.

Departure from flatness of a surface. Defined as the reciprocal of the radius of curvature.

a nonangular deviation of a straight line, as in greater and lesser curvatures of the stomach; abnormal curvatures of the vertebral column include kyphosis, lordosis, and scoliosis

the deviation of an object or of space or of spacetime from a flat form and therefore from the rules of geometry codified by Euclid.

Mathematically, is the second derivative of terrain elevation. Is an important feature in shape analysis and is used to indicate convexity/concavity of a surface.

(medicine) a curving or bending; often abnormal; "curvature of the spine"

the rate of change (at a point) of the angle between a curve and a tangent to the curve

This is a mathematically-defined term which refers to the amount of roundness located at a point on a curve or surface. If a curve is flat, then its curvature is zero. As the curve becomes more rounded, the radius of curvature goes down and the curvature goes up. Curvature 'k' = 1 / rho, where rho is defined as the radius of curvature. These two values ('k' and 'rho') are inversely related.

A slight to extreme bend in the penis. (Also see Peyronie's disease).

The act of curving or bending. One of the characteristics of line.

The amount of departure from a flat surface as applied to lenses.

A condition in which the parison is not straight, but somewhat bending and shifting to one side, leading to a deviation from the vertical direction of extrusion. Centering of ring and mandrel can often relive this defect.

The rate of deviation of a curve.

Curvature refers to a number of loosely related concepts in different areas of geometry. Intuitively, curvature is the amount by which a geometric object deviates from being flat, but this is defined in different ways depending on the context. There is a key distinction between extrinsic curvature which is defined for objects embedded in another space (usually a Euclidean space) in a way that relates to the radius of curvature of circles that touch the object, and intrinsic curvature which is defined at each point in a differential manifold.
