Webster's 1828 Dictionary
REACT
v.t.[re and act. ] To act or perform a second time; as, to react a play. The same scenes were reacted at Rome.
REACT
v.i. 1. To return an impulse or impression; to resist the action of another body by an opposite force. Every elastic body reacts on the body that impels it from its natural state.
2. To act in opposition; to resist any influence or power.
REACTED
pp. Acted or performed a second time.
REACTING
ppr. Acting again; in physics, resisting the impulse of another body.
REACTION
n. 1. In physics, counteraction; the resistance made by a body to the action or impulse of another body, which endeavors to change its state, either of motion or rest. Action and reaction are equal.
2. Any action in resisting other action or power.
Webster's 1913 Dictionary
REACT
REACT Re *act ", v. t.
Defn: To act or perform a second time; to do over again; as, to react a play; the same scenes were reacted at Rome.
REACT
REACT Re *act ", v. i.
1. To return an impulse or impression; to resist the action of another body by an opposite force; as, every body reacts on the body that impels it from its natural state.
2. To act upon each other; to exercise a reciprocal or a reverse effect, as two or more chemical agents; to act in opposition.
REACTANCE
REACTANCE Re *act "ance, n. [React + -ance. ] (Elec.)
Defn: The influence of a coil of wire upon an alternating current passing through it, tending to choke or diminish the current, or the similar influence of a condenser; inductive resistance. Reactance is measured in ohms. The reactance of a circuit is equal to the component of the impressed electro-motive force at right angles to the current divided by the current, that is, the component of the impedance due to the self-inductance or capacity of the circuit.
REACTANCE COIL
REACTANCE COIL Reactance coil (Elec.)
Defn: A choking coil.
REACTION
Re *ac "tion, n. Etym: [Cf. F. réaction.]
1. Any action in resisting other action or force; counter tendency; movement in a contrary direction; reverse action.
2. (Chem. )
Defn: The mutual or reciprocal action of chemical agents upon each other, or the action upon such chemical agents of some form of energy, as heat, light, or electricity, resulting in a chemical change in one or more of these agents, with the production of new compounds or the manifestation of distinctive characters. See Blowpipe reaction, Flame reaction, under Blowpipe, and Flame.
3. (Med. )
Defn: An action included by vital resistance to some other action; depression or exhaustion of vital force consequent on overexertion or overstimulation; heightened activity and overaction succeeding depression or shock.
4. (Mech. )
Defn: The force which a body subjected to the action of a force from another body exerts upon the latter body in the opposite direction. 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. Sir I. Newton (3d Law of Motion ).
5. (Politics )
Defn: Backward tendency or movement after revolution, reform, or great progress in any direction. The new king had, at the very moment at which his fame and fortune reached the highest point, predicted the coming reaction. Macaulay. Reaction time (Physiol.), in nerve physiology, the interval between the application of a stimulus to an end organ of sense and the reaction or resulting movement; -- called also physiological time. -- Reaction wheel (Mech. ), a water wheel driven by the reaction of water, usually one in which the water, entering it centrally, escapes at its periphery in a direction opposed to that of its motion by orifices at right angles, or inclined, to its radii.
REACTIONARY
REACTIONARY Re *ac "tion *a *ry, a.
Defn: Being, causing, or favoring reaction; as, reactionary movements.
