Scalars are specified by a magnitude completely while vectors need a magnitude and one direction for their specification.
Any Physical quantity is a tensor.
Tensors of rank 0 are called scalars. They can be specified only by a magnitude. (examples include mass, work, current, etc.)
Tensors of rank 1 are called vectors. They can be specified by a magnitude and a direction. (examples include force, displacement, current density etc.)
There are tensors of rank 2, 3.....in mathematics.
Most common examples of rank 2 tensors in physics are moment of inertia and effective mass of a particle.
