What are Tensor Quantities?

Answer: A tensor is a variable that has a quantity, a path, and a surface where it operates or is described about its reference frame. Each line location in a vector field has its tensor. Stress, Moment of Inertia, Strain, Electromagnetism, and Conductivity are examples of tensor variables.

The proportionate change in mass is what strain is.

A scalar value is perhaps the second moment.

Since a chunk of metal produces energy of 2 watts mostly in the x-direction, conductance, whether electric or heat, is a tensor.

Because we can’t define the behavior of an electromagnetic current in a 3D object without describing the plane, electromagnetic is a tensor quantity.
