What's the difference between curvature and curve?

Curvature


Definition:

  • (n.) 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.
  • (n.) 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.

Curve


Definition:

  • (v. i.) To bend or turn gradually from a given direction; as, the road curves to the right.
