Motion

of a bomb or ball. The progre which a bomb or ball makes through the air may be said to consist of three sorts, after it has been delivered out of the mortar, or emitted from a gun or musquet. These are:— The violent MOTION , or first explosion, when the powder has worked its effect upon the ball, so far as the bomb or ball may be supposed to move in a right line. The mixed MOTION , or yielding impulse, when the natural weight of the bomb or ball begins to overcome the force which was given by the gunpowder. The natural MOTION , or exhaustion of the first impulse. This occurs when the bomb or ball is falling to the ground. To MOTION a thing , to propose it in a military or civil meeting.
