Emergence, interaction, expression, affect, potential, tendencies, capacities. What is happening when a vibration motor is attached to a power source and forces the movement of another physical property (elastic band or metal wire)? The motor can turn an unbalanced mass at a variable speed when attached to power and control (potentiometer, Arduino). This turning motion has the capacity to send waves across fields of nearby objects – the turning motion itself is a tendency of the vibration motor. The tendency is emergent from the motor due to the interaction of the parts that produce it as well as the addition of voltage. Addition? Are ‘addition’ and ‘subtraction’ emergent properties? Spin the motor fast enough or place it in an environment of extreme high temperature and other tendencies will emerge, flowing as liquid metal from the motor. The motor only has the potential to vibrate objects if other objects susceptible to those forces actually exist. Interaction and maybe intra-action at play in the objects inner workings.
