A uranium-238 atom can break up into a thorium-234 atom and a particle called an alpha particle, αα-4. The numbers indicate the inertias of the atoms and the alpha particle in atomic mass units (1 amuamu = 1.66 ×× 10-27-27 kgkg). When an uranium atom initially at rest breaks up, the thorium atom is observed to recoil with an x component of velocity of -2.5 ×× 1055 m/sm/s.
