Study Notes
Section 8.1 - Vectors
- Objective: To add, subtract, and identify equal, opposite, and parallel vectors geometrically.
- Vector Definition: A quantity with both magnitude (length) and direction (angle with the positive x-axis).
- Methods for Vector Addition/Subtraction:
- Parallelogram Method
- Triangle Method (Tip-to-Tail)
- Opposite Vectors: Same length, but opposite direction.
- Equal Vectors: Same length, and same direction.
- Parallel Vectors: Same or opposite direction.
- Resultant Vector: The sum of two or more vectors.
- Components of a Vector: Each vector has a vertical and horizontal component.
- Example: A 6.2 cm vector at an 81° angle to the x-axis has a horizontal component of 0.97 and a vertical component of 6.1.
- Scalar: A physical quantity described by a single real number (magnitude only), examples include speed.
- Vector vs. Scalar: Vectors have both magnitude and direction, scalars have only magnitude.
- Zero/Null Vector: The resultant when two opposite vectors are added. It indicates equilibrium.
