Drawing Force Diagrams
Draw and interpret force diagrams showing forces as labelled arrows — where the arrow's length represents the force's magnitude and its direction shows which way the force acts; show multiple forces on one object; identify from the diagram whether forces are balanced (equal arrows in opposite directions, no resultant) or unbalanced (arrows of different sizes, producing a resultant); represent the resultant with a single arrow
Typical age: 7–12 years
“If your child is asked to draw a diagram of all the forces acting on a stationary book on a table, can they draw two arrows — one pointing down for gravity and one pointing up from the table — and explain why, if they're balanced, the book doesn't move?”

- Balanced & Unbalanced ForcesREQUIRED
Investigating balanced and unbalanced forces requires drawing force diagrams to record and analyse experimental findings
- Resultant ForcesREQUIRED
Forces as vectors with magnitude and direction is the formal underpinning of the force arrow representation
- Gravity & Falling ObjectsREQUIRED
Explaining gravity as a downward force requires representing it as a downward arrow in a force diagram
- Pushes & Pulls
Understanding pushes and pulls as forces is supported by the arrow representation of magnitude and direction
- Contact & Non-Contact Forces
Distinguishing contact and non-contact forces is clarified by drawing force diagrams showing where arrows originate
- Air Resistance & FrictionREQUIRED
Identifying and explaining air resistance and friction requires drawing force arrows to show opposing forces
