摘要
由碰撞力的计算公式入手,推出自由落体与地面相互作用力的计算公式为F=m(H/h)g,其中H和h分别为物体下落时刻和触地时刻质心离地面的高度。
From the formula of the collision, we can derive the formula of the interaction between the free falling object and the ground is F=m H/h g,H and h respectively stand for the height from the centre of mass to the ground for the moment of the object falling and touching me ground.
