Tensor is nothing but second degree vectors.

Tensor due to magnitude changes with different directions!

When there is no direction , only magnitude , M.I. is considered as a scalar.
When there is one direction & magnitude , it is a vector.
And when there are different magnitudes in diff. directions, it is a tensor(having more than one direction)
Hope its clear now.

Why the pressure is a tensor quantity?

What is the definition of moment?

Scalar = magnitude and no direction.
Vector = magnitude and one direction.
Tensor = magnitude and different direction.
Vector = magnitude and one direction.
Tensor = magnitude and different direction.

Tensor: Those physical quantity whose magnitude are different in different direction.
So, the moment of inertia is tensor.
So, the moment of inertia is tensor.

Moment of inertia is neither a scalar, nor a vector.
Some physical quantities which are neither scalars nor vectors which is called as 'tensors'.
So, Moment of inertia, pressure, stress, density, dielectric current, density, etc. are tensors.

Tensor means a quantity having magnitude and more than one direction. M.I has no direction. So it is scalar.

When I took classical mechanics we were given definitions for an object's moment of inertia, which I understand to be a scalar quantity that describes that objects tendency to resist rotation about a fixed axis either about, or some distance from its center of mass.
I was recently reading about how an object's moment of inertia can also be described as a tensor quantity when the axis of rotation is not fixed, but arbitrary.
