Vector Diagram Maker

What is a vector diagram?

A vector diagram represents quantities that have both magnitude and direction. Arrows encode those properties under a stated convention. In head-to-tail addition, the resultant runs from the first tail to the final head. In a parallelogram construction, it is the diagonal from the shared origin.

When to use it

Use it to explain force, velocity, or displacement addition within one consistent type of quantity. It is especially useful for seeing why vector addition differs from simply adding the lengths of two arrows.

What to include

1. Compatible quantities. Combine vectors with matching physical meaning and units.
2. A direction convention. State the coordinate axes, angle reference, or compass directions.
3. A declared scale. Give a scale for measurement or label the figure schematic; do not infer precision from its appearance.
4. Correct construction. Keep each vector's direction and length when translating it for head-to-tail addition.
5. A checked resultant. Draw it between the correct endpoints and verify its magnitude and direction using the supplied values.

Build it with MyMap

MyMap can draft the construction you describe and label the vectors and resultant. The example shows a parallelogram with A, B, and R = A + B. It is a schematic without numerical magnitudes, so its displayed arrow lengths should not be used as measured data.
