What do you mean by tensor?
In NCERT Class 11 Physics chapter 4 notes the term tensor refers to a physical quantity that has no direction. Instead, it has a variety of values pointing in diverse directions. As a result, it is neither a scalar nor a vector quantity. A moment of inertia of any object, for example, has no direction but a variety of values in different directions. As a result, it is neither a scalar nor a vector quantity. It is an illustration of a tensor. Tensors include stress, density, strain, and refractive index, among others.
