The height you would reach by "letting go" up a long slope without braking. Or, if you were to hit a wall the impact force would be the same as falling from this height. This number increases as a speed squared, and is useful for safety considerations.

高于地面的高度,您的势能将等于您当前的动能。 换句话说,你的速度等于你从这个高度下降后的速度(忽略空气阻力)。 同样,它是仅使用您的动能含量直线上升所达到的高度您在不刹车的情况下“放手”爬上长坡时会达到的高度。或者,如果您撞到墙上,冲击力将与从这个高度坠落相同。
这个数字随着速度的平方而增加,对于安全考虑很有用。
