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.
Force is a quantitative description of an interaction that causes a change in an object's motion. An object may speed up, slow down, or change direction in response to a force. Objects are pushed or pulled by forces acting on them. Contact force is defined as the force exerted when two physical objects come in direct contact with each other. Other forces, such as gravitation and electromagnetic forces, can exert themselves even across the empty vacuum of space.
