Resultant force

The resultant force is the vector sum of all individual forces acting on a body, and it determines the body's translational acceleration by Newton's second law. It is used to replace a system of forces with a single equivalent force in statics and dynamics.

\mathbf{F} = \sum_{i=1}^{n} \mathbf{F}_i

What the symbols mean

resultant force vector (N)
the i-th individual force vector acting on the body (N)
number of forces acting on the body
index labelling each force, from 1 to n
