11?
same speed because of same loss of PE
time different becasue different path

The force exerted on the drone by air is equal to the weight of the drone. There is no net force exerted on the drone. According to the Newton’s first law, if there is no net force exerted on the drone, it would keep at rest and afloat. (Due to its inertia)

Yes, mainly heat loss by conduction

睇錯咗佢speed係問張圖入面嗰個moment嘅speed,圈錯咗D

就係諗緊different path/distance係咪一定唔可以same time
先快後慢vs先慢後快
諗唔到點樣qualitatively prove
