(ĕ-kwā'zhŭn mō'shŭn)
1. An expression of Newton's second law that relates forces, displacements, and their derivatives for a mechanical system.
2. For the respiratory system, an equation that relates the forces involved in breathing to the displacements they produce. Typically, pressure differences are used to represent generalized forces and volume changes are used to represent generalized displacements. The simplest equation of motion written for the lungs states that the change in transpulmonary pressure is equal to the sum of an elastic term plus a flow resistive term: transpulmonary pressure change = elastance × tidal volume + resistance × change in flow.

To minimize the influence of pre- and post-occlusion target velocity information, uniformly accelerated motion, or randomized duration of the blanking periods were used in further studies [[3]], though predictable target trajectories were used.
That the situation is somewhat surprising, yet the result quite simple, helps to underscore both the great benefit and the great beauty of applying the basic ideas of uniformly accelerated motion in this two-dimensional case.
And not only in the phenomena of the pendulum did he discover regularity; the investigation of motion along a sloping plane convinced him after many measurements that all phenomena of gravity could be described in the most simple way by means of uniformly accelerated motion.
