Weight.
Newton's second law is F = ma, which gives force directly for a known mass and acceleration. Weight is the gravitational force (W = mg), so it can be obtained directly. Velocity and position require integrating acceleration over time; direction is not a scalar quantity directly calculated by the law (though the law does give the direction of the acceleration as the direction of the net force).
