The product of the adjusting physician's mass and acceleration does not quantify the adjustive force as popularly believed, an error stemming from a misunderstanding of Newton's second law. In this paper, a gedanken experiment illustrates the misapplication of F = ma and suggests that the adjustive force depends on the impact velocity, mass of the doctor, and intrinsic physical properties of the doctor and patient.
调整医生的质量与加速度的乘积并不能像普遍认为的那样量化调整力，这一错误源于对牛顿第二定律的误解。在本文中，一个思想实验说明了F = ma的错误应用，并表明调整力取决于撞击速度、医生的质量以及医生和患者的固有物理属性。
