Force is a vector. We get force from time derivative of momentum and momentum is a vector because velocity is a vector which is time derivative of displacement which is again a vector. In simple words-force has both magnitude and direction and hence it is a vector quantity.
A force in mechanics is a concept that has both a size and a direction. The net force acting on an object is the sum of the forces onto the object, taking into account both their sizes, and their directions. For example, if an object has two forces acting on it, with equal sizes but in opposite directions, then the net force will be zero (technically: a null vector). If instead the forces are of equal size and in the same direction, then the net force is equal to twice either force.
