Quantities that possess magnitude but require two or more directional aspects are called what?

• A. Vector Quantities
• B. Tensors
• C. System of Forces
• D. Scalar Quantities

Answer: (B)

Quantities in physics are described by how much there is and how that amount relates to direction. Scalars have only magnitude, so no directional information is needed. Vectors have magnitude plus a single direction, enough to specify their effect along one line in space. When a quantity requires describing how it relates across multiple directions—how it acts when you consider orientations in more than one axis—you need a tensor. A tensor encodes relationships that involve two or more directional components, such as how stress or inertia depends on orientation in a material. That multi-directional dependence is what sets tensors apart from scalars and vectors. So, for quantities that have magnitude but require two or more directional aspects, tensors are the appropriate description.
