→Forces as Vectors
===Forces as Vectors===
: [[Force]]s have both [[magnitude]] and direction so they are considered [[vector]]s.
====Positive and Negative Direction====
: When two [[force]]s act in opposite directions, along a line, one direction is chosen to be a [[Positive (Number)|positive]] direction and the other is chosen to be a [[Negative (Number)|negative]] direction, just as on a [[Number Line|number line]] in [[maths]].

====Forces on a Free Body Diagram====
: To show [[force]] [[vector]]s a [[Free Body Diagram]] can be used, this indicates the [[magnitude]] and direction of the [[force]]s.
