Study Notes
Vector Representation
- Vectors are represented by arrow-tipped line segments.
- The length of the arrow represents the vector's magnitude.
- The arrowhead points in the direction of the vector.
Drawing Vectors
- Choose a scale to represent the magnitude of the vector (e.g., 1 cm = 4 km).
- Calculate the length of the arrow based on the scale and the vector's magnitude.
- Draw an arrow with the calculated length pointing in the specified direction.
Key Concepts
- Vectors can be represented algebraically (using variables) or geometrically (using arrows).
- Geometric representations visualize both the magnitude and direction of a vector.
- To draw a vector accurately, clearly specify the scale and reference direction in the diagram.
- Use rulers for precise measurement when drawing vectors.
