Vector Addition
Interactive simulation — adjust parameters and watch the visualization update in real time.
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.
Key equations
A_x = |A| cos θ, A_y = |A| sin θ
R_x = A_x + B_x, R_y = A_y + B_y
