鈔票實驗?

Can anyone translate this experiment to English or only the first three sentences?

1.能說出人類的反應時間大約幾秒。

2.能說出為什麼我們要預留安全時間與安全空間?

3.能說出牛頓慣性定律的大概內容。

千元大鈔明明放在我們的手指間,為什麼很不容易夾住呢?這是因為眼睛看著鈔票落下,到真正動手去夾鈔票,大約需要0.2秒的反應時間,但在這0.2秒裡,鈔票已經下降20公分左右了,所以我們很不容易夾住它,這時,如果手能迅速下降20至30公分再夾,或許可以提高夾到鈔票的機會。

    1.It shows the human reaction time.

    2.It shows the reason why we need to prepare some 'safety time' and 'safety space'

    3.It shows a brief idea of Newton's First Law(Inertia).

    Why is it so hard to grip the thousand note even it is just between our fingers? This is because from the moment you see the note falling to the moment that your fingers really start to move, it takes 0.2 seonds as reaction time. However, in this 0.2 seconds of reaction time, the note has already falled for 20 centimeters. This is why it is so hard to catch it. At that time, if your hand can move downwards for 20 to 30 cm and then start to grip, may be it would have a higher chance of gripping the note.

    (Don't know the special term for that seond sentence)
