For section 5.1.2 Physical System Description - you could mention some related use of the libraries in 2D games. However if the use case or modules don't contain functionality in your implementation or you are not certain yet. Perhaps ask @smiths what would be appropriate here
5.1.2 Physical System Description
This project is to implement a set of physics libraries. Hence a physical system description
might not be applicable???

Other than that, good job! Your SRS documentation appears to be quite good and complete.
