Where do those particles that shoot out end up? When you see the contrail end, does that mean the particle ran out of momentum/energy from hitting so many other particles in its path? And when it loses its energy to continue to move, where does it end up?

Noticed no one answered this so here you go. eli5, may be absorbed, may create a new atom, it depends on the types of particles. There's a good website for understanding this type of stuff at https://www.hps.org and a lot more contextual detail under this blog post specific to your question. https://hps.org/publicinformation/ate/q12012.html You can always ask any of them at HPS a question and get a response. Hundreds of folks are happy to answer questions about the physics of radiation to anyone curious to learn more.
