Magnitude : size/length • Direction: direction from one place to another (has 2 parts – an angle and a cardinal direction) The notation of a vector is a single letter in bold (v or u, etc)or a single letter with an arrow on top A Vector is a directed line segment that has two and only two defining characteristics:
Vectors are made up of the Horizontal (x) and Vertical (y) Components Express the vector coordinates below as ordered pairs in simplest radical form. Components
If a position vector has length 8 cm and direction 60°SW, then find the horizontal & vertical components.
To add vectors in component form, just add the horizontal components and the vertical components. To add vectors graphically, just play “follow the leader.” Then draw a new vector from the start of the first to the end of the second. The new vector is called the resultantor displacement vector.
