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.
Confidence votes 73. Normal force is the force of a surface acting on an object( the normal force is perpendicular to the plane of contact). This force is directly related to the force of gravity, as the third law of newton state that when a force is applied to an object it will react with an equal force in the opposite direction.
