... When a rigid body rotates about a fixed axis perpendicular to the plane of the body at point O, the body’s center of gravity G moves in a circular path of radius rG. Thus, the acceleration of point G can be represented by a tangential component (aG)t = rG α and a normal component (aG)n = rG ω2. Sinc ...

... The frame which rests (or moves with constant velocity) in respect to the distant „stable” stars is inertial. The Earth in many practical cases can be considered as inertial. We should remember however, that the Earth rotates around its axis which gives a small acceleration. On the equator one gets ...

... about the “volume” in this space. In particular, we found that this volume A. is always zero. B. can be written in terms of a strain tensor. C. must remain constant as the system evolves. D. undergoes oscillations about its principal axes. E. has a “center of mass” that moves with constant velocity. ...
