SUMMARY
The mechanical energy required for an average-sized individual weighing 80 kg to climb nine flights of stairs, with each floor approximately 3 meters high, totals 23,520 Joules. This calculation is derived using the potential energy formula PE = mgh, where g is the acceleration due to gravity (9.8 m/s²). The result equates to roughly 4 kilocalories, prompting discussion on the efficiency of stair climbing for weight loss. The calculations presented are accurate, confirming the energy expenditure involved in this physical activity.
