WebCentripetal force is perpendicular to tangential velocity and causes uniform circular motion. The larger the centripetal force F c, the smaller is the radius of curvature r and the sharper is the curve. The lower curve has the same velocity v, but a larger centripetal force F c produces a smaller radius r ′ r ′. WebDefinition. Let be a point on the surface inside the three dimensional Euclidean space R 3.Each plane through containing the normal line to cuts in a (plane) curve. Fixing a choice of unit normal gives a signed curvature to that curve. As the plane is rotated by an angle (always containing the normal line) that curvature can vary. The maximal curvature and …
