The Abraham‐Lorentz equation of motion for a charged particle admits ‘‘runaway’’ solutions which violate the law of inertia. The integrodifferential form of the Abraham–Lorentz equation eliminates the runaway solutions, but in so doing introduces ‘‘preacceleration’’ which violates the principle of causality. Here it is shown that there exists a form of the equation of motion for a nonrelativistic charged particle which is in accord with both the law of inertia and the principle of causality.
