A quantity which has magnitude only is a . Examples are length, and mass.
A quantity which has both magnitude and direction is a . Examples include displacement, velocity and .
The parallelogram Law states that if two vectors are represented by two sides of a parallelogram, then the between them represents their resultant.
The Triangle Law states that if two vectors are drawn with the from the first touching the of the second, then a vector from the tail of the first to the head of the second is the vector.
Any vector may be resolved into two , usually at right angles to each other. These are called components. A vector v may be resolved into along the x-axis, and along the y-axis, where θ is the angle between v and the x-axis.
A vector has no component at angles to itself.
