Objects in the Universe are subject to the continued actions of forces (accelerations) because of rotation, translation, electromagnetic, and gravitational interactions with nearby and distant surrounding bodies.

Under many circumstances, we may neglect external accelerations because they might be of low magnitude compared to local accelerations. But that doesn't mean that they don't exist. Moreover, subtle differences in acceleration are the cause of constant and dynamic deformation of masses and changes in motion that can't be ignored.

In this book, there are several cases that show with clarity what accelerations produce what effect and in what amount. The differential equations of a force in space are derived for those of you who want to make heavy calculations.
