The two vectors (the velocity caused by the propeller and the velocity of the wind) result in a slightly slower ground speed heading a little East of North. If you watched the plane from the ground it would seem to be slipping sideways a little.Definition of a vector. A vector is an object that has both a magnitude and a direction. Geometrically we can picture a vector as a directed line segment whose length is the magnitude of the vector and with an arrow indicating the direction. The direction of the vector is from its tail to its head.A unit vector is a vector that has a magnitude of one. A vector representing a unit vector is usually also boldface although it will have a carat () above it to indicate the unit nature of the variable. The unit vector x when written with a carat is generally read as x-hat because the carat looks kind of like a

Vectors are equal if they have the same magnitude and direction regardless of where they are. So A negative vector has the same magnitude but the opposite direction.A vector with magnitude 0 is called the zero vector written 0. A vector with magnitude 1 is called a unit vector . Vectors are equal if they have the same magnitude and the same direction.Simply put a vector is 2 dimensional. Think of speed - it is only one dimensional. It is not a vector it is a scalar. It is measured in a scale most commonly noticed when inside a vehicle.

The row vectors with a fixed number of columns form a vector space. Coordinate vector the n-tuple of the coordinates of a vector on a basis of n elements. For a vector space over a field F these n-uples form the vector space (where the operation are pointwise addition and scalar multiplication).A vector has both magnitude and direction. We use vectors to for example describe the velocity of moving objects. In this video youll learn how to write and draw vectors.
