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