Which type of quantity does distance represent?

• A. Vector quantity
• B. Scalar quantity
• C. Dimensional quantity
• D. Complex quantity

Answer: (B)

Distance represents a scalar quantity because it has only a magnitude and no direction. Scalars are measured in terms of size or absolute values, which is exactly what distance provides. For example, when you say that an object is 10 meters away, that measurement tells you how far it is without any reference to the direction in which it is located. In contrast, vector quantities have both magnitude and direction, such as velocity or displacement. Dimensional quantities refer to the type of physical quantity characterized in terms of basic dimensions (like mass, length, time) and are often used to understand how quantities relate to one another in physics. Complex quantities involve both a real and an imaginary part, which is not applicable here. Thus, the definition of distance aligns solely with that of a scalar quantity.
