Triple axis accelerometers attached to the central balls of a Newton's cradle pendulum reveal, along with the expected horizontal acceleration, an unexpected vertical acceleration following the impact with the first ball. This effect can be explained through a switch in the initially vertically oriented kinetic dipoles in each ball to a horizontal direction as a result of the force of impact. The central balls experience a vertical acceleration because, for a moment, the balls are less heavy since not all their kinetic dipoles continue to push downwardly as before the impact. After transmitting the impact force to the next ball, each central ball switch back its horizontal kinetic dipoles to the initial vertical orientation. The delay between the horizontal and vertical signals provided by the accelerometers also reveal a relaxation time of the kinetic dipoles' change of direction.
