- Forces acting on the same line can either be agreement forces, where direction and verse align, or conflicting forces, where the line coincides with the force module of greater magnitude.
- Competing forces, such as those acting perpendicularly on a boat, result in a vector sum determined by the parallelogram rule.
- Parallel agreement forces result in a force equal to the sum of the forces, sharing the same direction, but require a different calculation method as action lines do not intersect.
- Parallel conflicting forces maintain the same direction as the applied forces, resulting in a force equal to the difference of the magnitudes, applied at the extreme.
- Equations such as R = F1 + F2 for agreement forces and R = F2 - F1 for conflicting forces are used to calculate resultant forces.
