Common Mistakes

X Adding magnitudes instead of vectors Add components separately |a| + |b| ≠ |a + b|

X Forgetting negative signs −a means reverse direction −(3,4) = (−3,−4)

Quick Recall Flashcards

Vector Magnitude

|v| = √(x² + y²). Length of vector using Pythagoras. Always positive!

Vector Addition

Add components separately. (a,b) + (c,d) = (a+c, b+d). Represents combined movement.
