Because it is a strong pressure wave that carries energy with it, which causes a large disturbance in the air as the shock passes through it. The disturbance includes a drastic increase in the air pressure, density, temperature, as well as the velocity of the air (v2).
Thanks for your video. That helps me understand the moving shock problem, especially the different reference frames concept.
Thanks
Why does the moving shock induce v2
