Study Notes
Vector Quantities
- Vector quantities have both magnitude and direction
- Scalars have magnitude only
- Vectors are represented graphically by a line with an arrow
- The length of the line represents the magnitude
- The arrow head indicates the direction of the vector
Addition of Vectors
- Collinear vectors are added according to their directions (+ or -)
- Non-collinear vectors are added graphically using the tail-to-head or polygon method
- The resultant vector has the combined effect of the two (or more) vectors added.
Components of Vectors
- Vectors can have components along different directions
- For example, a vector in 2D space has components along the x-axis and y-axis.
- Resultant vector is obtained by vector addition.
Directions & Notation
- Directions use a common compass format
- Directions in coordinate planes are often given using angles relative to the x and y axes.
