Noun:
A curved line on a graph that represents data. A curve is the trace of a point whose direction of motion changes. Curves can be formed by various means such as bending or causing to bend a straight line, turning sharply and abruptly changing direction, or extending in curves and turns. The property possessed by the curving of a line or surface can vary greatly depending on the purpose of the curve. For example, a road curve might be designed to reduce wind resistance, while a mountain road curve might be designed to provide a more challenging driving experience. In addition to being used in mathematics and physics, curves are also used in everyday life to describe the path of objects moving through space. Examples include the trajectory of a ball thrown with spin so that its path curves as it approaches the batter (a baseball curve), or the twisted path of smoke curls up at the ceiling after being smoked (a cigar curve). In architecture and design, curves can also form an arch or curve, such as an archway or an architectural feature. In these cases, the curvature of the shape is often used to create a sense of beauty or grandeur.
