half-arc

On this hypothesis, the hammering of the ultra-mundane corpuscles on the bob confers its kinetic energy, on the one hand, and takes it away on the other; and the state of potential energy means the condition of the bob during the instant at which the energy, conferred by the hammering during the one half-arc, has just been exhausted by the hammering during the other half-arc.

Three hundred feet from point to point, and no less than five hundred and fifty round the curve, that half-arc soared touching the bridge it supported for a space of fifty feet only, one end resting on and built into the parent archway, and the other embedded in the solid granite of the side of the precipice.

So that the sum of the phenomena may be stated thus: At the summit of either half-arc of its swing, the bob has a certain amount of potential energy; as it descends it gradually exchanges this for kinetic energy, until at the centre it possesses an equivalent amount of kinetic energy; from this point onwards, it gradually loses kinetic energy as it ascends, until, at the summit of the other half-arc, it has acquired an exactly similar amount of potential energy.

The blue-clad arms of one of them were twisted upward in a half-arc, encircling nothing; and as the wheels jolted over the rutted cobbles these two bent arms joggled and swayed drunkenly. The other's head was canted back so that, as we passed, we looked right into his face.
