The Unit Vector
Vector DH is the unit vector that represents vector AB. Drag A, B, and vector v to see how the changes affect the unit vector. Note that the slope and magnitude of both vectors are provided.
1. How does changing A or B affect vector DH?
2. If you drag and move v without changing the relative positions of A and B, does the component vector DH change?
3. What is the relationship between the magnitude of vectors AB and DH? The slope?
4. Which characteristic of a vector does slope indicate?
5. Explain how you could change vector AB without changing its component vector. List at least 2 ways.
