Transcribed Image Text:Title: Understanding Resultant Vectors
### Vector Addition Practice
**Objective:** Learn how to draw the resultant vector for given vector pairs.
### Given Vector Operations:
1. \( \vec{A} + \vec{B} \)
2. \( \vec{B} + \vec{A} \)
3. \( \vec{A} - \vec{B} \)
4. \( \vec{B} - \vec{A} \)
5. \( 2\vec{A} - \vec{B} \)
### Diagram Explanation:
- Two vectors are represented by arrows:
- **Vector A**: Shown as an arrow pointing slightly downward.
- **Vector B**: Shown as an arrow pointing almost directly upward.
### Rules for Adding Vectors:
- **Rule 1:** Add vectors head (arrow tip) to tail (origin of the arrow).
- **Rule 2:** The resultant vector goes from the tail of the first vector to the head of the last. *(Place a marker at the tail of the first vector for clarity.)*
- **Rule 3:** The order of adding vectors doesn’t matter, but maintaining correct direction is crucial—ensure to use proper reference degrees.
- **Rule 4:** A negative sign with a vector indicates it moves in the opposite direction. *(Think of this as algebraic addition.)*
- **Rule 5:** On a Cartesian Coordinate System, draw the angle of the resultant by rotating counterclockwise from the positive x-axis (0 degrees) to the resultant direction. Assume:
- \( +x = 0 \) degrees
- \( +y = 90 \) degrees
- \( -x = 180 \) degrees
- \( -y = 270 \) degrees, unless stated otherwise.
### Conclusion
Understanding how to determine and draw resultant vectors using these rules is fundamental in vector mathematics and physics, simplifying complex vector interactions into visually comprehensible forms.
