If a rocket is fired upwards to launch a satellite in its orbit, then the two forces acting on the rocket immediately after leaving the launching pad are gravitational force of the earth that acts in the downward direction and frictional force of air that acts in an opposite direction to the motion of the rocket.
Gravitational force of earth is a force that is exerted by the earth on all objects present in it. When the rocket starts moving in the upward direction, Earth exerts a force which is equal to the weight of the rocket in the downward direction.
Frictional force of air is the force resisting the relative motion of any object that moves in air. When the rocket starts moving in the upward direction, the air exerts an equal and opposite force on the rocket, thus resisting its motion.
