Stress, strain and elastic potential energy

Stress, strain and elastic potential energy:

Tensile stress is defined as the force applied divided by the cross-sectional area (F/A). Units Nm^-2 or Pa.

Tensile strain is defined as the change in length (the extension) divided by the original length. It doesn't have any units.

As a greater and greater tensile force is applied to a material, the stress on it increases.
