      Newton: (1) Every body perseveres in its state of rest or
      of moving uniformly in a straight line, except so far as
      it is made to change that state by external force. (2)

      and takes place in the direction in which the force is
      impressed. (3) Reaction is always equal and opposite to
      action, that is to say, the actions of two bodies upon
      each other are always equal and in opposite directions.

Dalton's law
     n 1: (chemistry) law stating that when two elements can combine
          to form more than one compound the amounts of one of
          them that combines with a fixed amount of the other will
          exhibit a simple multiple relation [syn: {law of
          multiple proportions}]
     2: (chemistry and physics) law stating that the pressure
        exerted by a mixture of gases equals the sum of the

        pressure of a gas in a mixture equals the pressure it
        would exert if it occupied the same volume alone at the
        same temperature [syn: {Dalton's law of partial pressures},
         {law of partial pressures}]
