An ingine or motor is a machine designed tae convert energy intae uiseful mechanical motion. Heat ingines, includin internal combustion ingines an freemit combustion ingines (such as steam ingines) burn a fuel tae create heat, which then creates motion. Electric motors convert electrical energy intae mechanical motion, pneumatic motors use compressed air an ithers—such as clockwirk motors in wind-up toys—uise elastic energy. In biological seestems, molecular motors, lik myosins in muscles, uise chemical energy tae create motion.
