The problem of the conservation laws in action at a distance interactions is approached
with a treatment based on the stated action for this type of interaction; The variational
method is used to find conserved quantities, which are identified with the usual ones
(energy, momentum) in agreement with the infinitesimal transformation used to variate
the action; As result is that the conserved quantities in this case have a sense different
from the usual one, because is not possible to identify energy or momentum in transit
between the interacting particles but these quantities must be interpreted like dynamic
quantities that are inherent to the world line of each particle, fact that motivates a new
interpretation of the importance of the conservation laws in the analysis of interactions.
