搖控直昇機在車內靜止在空中,當車剎車時的問題

在行駛的車中,搖控直昇機在車內靜止在空中,當車剎車時的問題
A直昇機在車內靜止空中須要向前加力嗎?
B當車剎車時,直昇機會向前定靜止?
C車由0到加速,在空中的直昇機會向後定同步向前?

在行駛的車中,搖控直昇機在車內靜止... implies the chopper is flying at the same velocity as the car (with both relative to the ground).

A) Newton's First Law of Motion* implies that every object in a state of uniform motion tends to remain in that state of motion when no external force is applied to it.

B) 剎車 without 剎機, the chopper would continue to fly (relative to the ground and the decelerated car) as stated by Newton's 1st Law.

C) 車由0到加速 + 直昇機在車內靜止 implies both the car and the chopper were initially stationary. What do you get when the car starts moving forward and the chopper remains stationary to the ground?

* 牛頓第一運動定律:當物體無受到外來力量左右,本來靜止嘅物體會一直靜止,而本來郁動緊嘅就會一直郁動,沿著直線保持住速度咁郁動。呢條定律又稱之為「慣性定律」。
