| Jan 10, 2019 at 10:19 | comment | added | David Schneider-Joseph | Don’t you mean they must get decelerated to their original speeds (i.e. magnitude of velocity), not velocity? The direction of the particle’s velocity vector can change in the process, no? And if so, doesn’t this impart momentum? | |

Added a second explanation.
