[Graph of Stopping Power vs Energy]
FIGURE 1
One would have a better chance at survival running rather than crawling across a highway. Similarly, the stopping power of a medium decreases as the kinetic energy of the traversing paricle increases, as seen in this plot of stopping power (energy loss per centimeter travelled) of antiprotons in water vs. their kinetic energy.
