👉 The counterior is a directional force that opposes the direction of motion or the applied force, effectively pushing against it. Unlike normal forces, which act perpendicular to the surface and are always balanced by an equal and opposite reaction force, the counterior acts parallel to the surface and can either enhance or counteract the applied force depending on its direction relative to the surface. For instance, when a car's tires push backward against the road (counterior), this force contributes to the forward motion of the car. In some mechanical systems, counterior forces are crucial for maintaining stability or controlling movement.
