|colspan= "2"|The two [[vector]] [[force]]s drawn to a 'scale' on a [[Scale Diagram]]. This scale is 1N = 1cm. The two [[force]]s can be added by placing the start of one [[vector]] [[force]] at the end of the other. This [[Scale Diagram]] shows that the two [[force]]s cancel one another out so the net [[force]] is zero.

The two [[force]]s can be added by placing the start of one [[vector]] [[force]] at the end of the other. This [[Scale Diagram]] shows that the two arrows add to make a length of 6.1cm, which represents 6.1N, in a direction of 35° down from the [[horizontal]].
