fast-moving particles colliding with slow-moving particles.

Explanation: Heat conduction transfers kinetic energy from hotter (more energetic) particles to cooler ones through collisions. In a metal fork, free electrons (and lattice vibrations) carry energy by colliding with and exciting slower particles further along the fork.
