Facets:
value: at the instant one particle
type: TEMPORAL
Source sentences:
text: In these processes energy and momentum are conserved overall (that is, the totals remain the same, in accordance with the basic laws of physics), but, at the instant one particle emits a photon and another particle absorbs it, energy is not conserved.
