Taking the several forces that act on an object as a reference, we can calculate and represent graphically the resultant force vector. The numerical result is obtained both in Cartesian coordinates and in polar coordinates.

The application includes several options:
- The forces can be entered in Cartesian coordinates or in polar coordinates.
- If the graphical representation goes out of the screen, we can change the scale of the vectors, from an order of magnitude of 1 N to 10.000N.
- We can choose the decimals of the final result (between 0 and 4).
