When a horse pulls a wagon, the force that causes the horse to move forward is the force
When the horse pulls the wagon, it pushes the ground in the backward direction. Due to the third law of motion, the ground exerts a forward force which has the same magnitude. As the backward force applied by the wagon is weaker than the force applied by the horse, the wagon moves in the forward direction.
