[冷知識分享] 遇到交通意外，跳車逃生時應該向前跳還是向後跳比較安全呢？

遇到這麼緊急的情況，生死攸關，千萬不能做錯決定，假如你決定朝車子行駛的方向跳出去的話，你實死無生，因為離開車子的身體會循「慣性法則」隨著車子的速度向前，身體會加速，然後狠狠的摔在地上，如果向後方跳的話，速度會相對抵消，著地時會減少一些撞擊力道。此外，向前跳的話，著地的時候，身體會向後仰，後腦撞到的危機性較大，死亡率亦較高。

(a) Unless you are travelling in extremely slow speed (5Km or less), otherwise your jump off speed is so slow in comparison to your forward speed.  The counter
effect is not significant.  OK this explain the speed aspect.公仔箱論壇! @$ w$ m$ J$ y5 h# `* J# }5 W
(b) Jumping direction: if you were in a car or a train carriage, you do not have a 6 U1 \- G" ]) F4 _/ F$ h
choice whether you are jumping forward or backward. You can only jump iside way or best a 45 degree against the forward angle.  Either angle will affect your
landing impact.  Do  not forget to Roll when the body hit the ground.
(c) Make sure when you jump, you are facing the forward direction. If you are
facing the away direction, the forward momentum will make you fall on the back
of your head first, it could be a fatal hit.
This is my 2 cents worth.

If you are carrying a forward momentum and when the body/ object landed, the
momentum will continue its direction unless affect by other external force. (Baisctvb now,tvbnow,bttvb+ x! n3 s3 g: ^! X$ g) H9 ^$ K2 b

the ground first unless you lean back when you jump off the moving object.
