Force and Moment from Modal Analysis

Hello,

I have extracted the results from modal analysis. The results look like the following picture.

As you seen in the table header, there are FX1, FY1, FZ1, MX1, MY1, MZ1 and FX2, FY2, FZ2, MX2, MY2, MZ2. So, I have two questions.

1. What does the number end of the FX, FY, FZ, MX, MY, MZ mean? 

2. Displacement of each modeshape as shown in modal analysis result based on mass normalization. So, whether the force and moment of the result are the actual loading or not. Do they have unit, such as N, N*m or dimensionless?

Thank in advance
