Read the result
Components tell you what happens in each axis. The drawn resultant shows the single movement that has the same overall effect.
Vector algebra
2D Vector Calculator
Add or subtract 2D vectors and read the resultant as both components and a direction.
Formula
(x1, y1) + (x2, y2) = (x1 + x2, y1 + y2)
Result
Worked substitution
Component calculations keep vector operations transparent.
Where it helps
Use this for displacement, velocity, force components, and quick resultant checks in plane problems.
Common slip
Subtraction is not the same as reversing both vectors. A - B means add the negative of B to A.
Try it
Choose B = -A. The resultant should be the zero vector and the direction should become undefined.
