NettetThe woman does 1764 J of work to move up the stairs compared with only 120 J to increase her kinetic energy; thus, most of her power output is required for climbing rather than accelerating. It is impressive that this woman’s useful power output is slightly less than 1 horsepower (1 hp = 746 W)! NettetAs it happens, 1 calorie = 4.184 joules, or 1 joule = .239 calories, so a common rule of thumb is to assume a GME of 23.9%, in which case the number of food calories (= Calorie, = 1000 calories = 1 kilocalorie) is roughly equivalent to 1 kilojoule.
