Direction Of Vector

Vector Fundamentals

• A vector diagrams the quantity and direction of distances, forces, velocities, and accelerations.
• Direction determines how applied quantities combine and interact.

Vector Representation and Addition

• A vector is diagrammed as an arrow, where the length indicates the quantity and the arrow's direction indicates the vector's direction.
• Applying a force of $10\,\text{pounds}$ and a force of $5\,\text{pounds}$ in the same direction produces a total force of $15\,\text{pounds}$.
