Vector Addition
Place vectors on a plane and see the resultant from head-to-tail or component addition. Reinforces magnitude, direction, and decomposition.
Who it's for: Physics and engineering prep; first-week vector skills.
Key terms
- vector
- resultant
- components
- head-to-tail
- magnitude
How it works
Vectors add component-wise: R = A + B means R_x = A_x + B_x and R_y = A_y + B_y. Geometrically, place the tail of B at the head of A (or use the parallelogram rule). The cyan arrow shows the resultant.
