Simplifying an Inclined Plane Problem. In the presence of friction or other forces (applied force tensional forces etc.) the situation is slightly more complicated.In geometry a normal is an object such as a line or vector that is perpendicular to a given object. For example in the two-dimensional case the normal line to a curve at a given point is the line perpendicular to the tangent line to the curve at the point.As explained above a vector is often described by a set of vector components that add up to form the given vector. Typically these components are the projections of the vector on a set of mutually perpendicular reference axes (basis vectors).

Check Your Understanding. 1. To test your understanding of this distinction consider the following quangraphicies listed below. Categorize each quangraphicy as being either a vector The normal vector often simply called the normal to a surface is a vector which is perpendicular to the surface at a given point. When normals are considered on closed surfaces the inward-pointing normal (pointing towards the interior of the surface) and outward-pointing normal are usually distinguished.Notice that the dot product of two vectors is a number and not a vector. For 3 dimensional vectors we define the dot product similarly

As we have seen vector addition and scalar multiplication can produce new vectors out of old ones. For instance we produce the vector A The gradient is a fancy word for derivative or the rate of change of a function. Its a vector (a direction to move) that Points in the direction of greatest increase of a function (intuition on why) Is zero at a local maximum or local minimum (because there is no single direction of increase The curl operator is defined and explained on this page. The curl (also called the rotation or rot) takes a vector input and returns a vector output which is a A mathematical discussion of curvature and torsion for physical applications.
