What is a Vector?
Definition and Characteristics of Vectors
- A vector is defined as an arrow, which represents a directed line segment characterized by a magnitude (value and unit), direction, and sense.
- An example illustrates a car moving 20 meters from the city center, demonstrating how to visualize changes in position using vectors.
- The magnitude of the vector refers to the distance traveled (20 m), while the direction indicates the path taken by the vector.
- Vectors can be represented graphically with any letter, provided that an arrow is placed above it to signify its vector nature.
- Key characteristics of vectors include:
- Point of application or origin
- Magnitude (intensity or module)
- Direction (the straight line along which the vector acts)
- Sense (indicated by the arrow's point showing positive or negative direction on a Cartesian plane).
