Physical compression is the result of the subjection of a material to compressive stress, resulting in reduction of volume.
tensile stress compressive stress shear stress
2.1.2. Compressive StressIf the bar is subjected to axial compression instead of axial tension, the stress developed at x-x is specifically called compressive stress pc.pc =R/A= P/A.Under compressive stress the bar suffers shortening.
The compressive stress allowed is 25N/mm2. However, the strength of a concrete element depends on the arrangement of loads. For compression, the element might buckle before it reaches its compressive stress.

In geology the term compression refers to a set of stresses directed toward the center of a rock mass. Compressive strength refers to the maximum compressive stressthat can be applied to a material before failure occurs. When the maximum compressive stress is in a horizontal orientation, thrust faulting can occur, resulting in the shortening and thickening of that portion of the crust. When the maximum compressive stress is vertical, a section of rock will often fail in normal faults, horizontally extending and vertically thinning a given layer of rock. Compressive stresses can also result in folding of rocks. Because of the large magnitudes of lithostatic stress in tectonic plates, tectonic-scale deformation is always subjected to net compressive stress.
The collision of objects will create compressive and possibly shear stress.
Yes.
Shortening
Yes, the characterisrtic strength of a concrete is the same as the compressive strength
