Adding Vectors Vectors can be combined by adding or subtracting them to produce the resultant vector The resultant vector is sometimes known as the ‘net’ vector (eg. the net force) There are...
Resolving Vectors Vectors are represented by an arrow The arrowhead indicates the direction of the vector The length of the arrow represents the magnitude Component vectors are sometimes drawn with...
Scalars & Vectors A scalar is a quantity which only has a magnitude (size) A vector is a quantity which has both a magnitude and a direction For example, if a person goes on a hike in th...
