| | Vector (spatial) - Wikipedia, the free encyclopedia |
 | | The magnitude of the vector is 15 N in both cases. | | | A common example of a vector is force — it has a magnitude and an orientation and multiple forces sum according to the parallelogram law. | | | For example, work depends on displacement, which is the difference of positions and therefore does not depend on the origin. |

| | Observe in the first example that the vector is said to have a direction of 40 degrees. | | | For example, a vector can be said to have a direction of 40 degrees North of West (meaning a vector pointing West has been rotated 40 degrees towards the northerly direction) of 65 degrees East of South (meaning a vector pointing South has been rotated 65 degrees towards the easterly direction). | | | Observe in the second example that the vector is said to have a direction of 240 degrees. |

| | Vectors |
| | Graphically, a vector is represented by an arrow, defining the direction, and the length of the arrow defines the vector's magnitude. | | | The reason for this introduction to vectors is that many concepts in science, for example, displacement, velocity, force, acceleration, have a size or magnitude, but also they have associated with them the idea of a direction. | | | Very often in vector problems you will know the length, that is, the magnitude of the vector and you will also know the direction of the vector. |

| | Vector Arithmetic |
| | The algebraic addition of vectors works because the sums of the components are the components of the sum. | | | Another way to look at this subtraction business is to define the negative of a vector as that vector, which when added to the original yields a null result. | | | Since a vector is defined by its magnitude and direction, changing its location in our reference frame without changing its direction or magnitude leaves it the same vector. |
