第一部分是研究固体球体垂直撞击液体表面时的运动。所形成的空气腔的形状被描绘并解释在潜在的流动和球体在这个阶段所经历的阻力进行测量。这些因素被发现的基础上的弗劳德参数的规模。在腔中开发的压力也被测量，并发现涉及大振幅的腔中的混响。第二部分研究了球体和其它形式的弹丸进入液体时所受的冲击力，并与理论进行了比较。还讨论了球体以斜角进入后弹飞的机理和受力情况。
Part I consists of a study of the motion of a solid sphere when it strikes a liquid surface vertically. The shape of the air cavity formed is delineated and explained in terms of potential flow and the resistance experienced by the sphere in this stage is measured. These factors are found to scale on the basis of a Froude parameter. The pressure developed in the cavity is also measured and found to involve reverberations in the cavity of large amplitude. In Part II the impact forces on the sphere and other forms of projectile on entry into the liquid are studied and compared with theory. The mechanism and forces involved when a sphere ricochets after entry at oblique angles are also discussed.
