... A brief review of the fundamental concepts of vector and tensor analysis necessary for the development is also made. After a presentation of the postulates used, a matrix notation which is most convenient for the four-dimensional formulation of the theory is developed. This notation is applied to de ...

Since the resultant forces are action-reaction pairs governed by Newton 's third law, they act in opposite directions so the two objects accelerate in the directi ...
