In an arrow representation of a vector, the arrow's [ ] represents magnitude and its arrowhead represents direction.
A
In an arrow representation of a vector, the arrow's length represents magnitude and its arrowhead represents direction.
B
For points with position vectors a\mathbf{a}a and b\mathbf{b}b, AB→=\overrightarrow{AB}=AB= b−a\boxed{\mathbf{b}-\mathbf{a}}b−a, while BA→=\overrightarrow{BA}=BA= a−b\mathbf{a}-\mathbf{b}a−b.
C
The magnitude is multiplied by ∣k∣\lvert k\rvert∣k∣.
D
It halves the magnitude and reverses the direction.
