The force that acts in the opposite direction of lift is weight, which is the force exerted by gravity pulling the object downward. It acts vertically downward from the center of mass of the object.
The fluid force that opposes lift is drag. Drag is the force that acts opposite to the direction of an object's motion through a fluid, such as air. It acts to slow down the object's movement, including an aircraft's forward motion.
Drag
The force that opposes lift is drag. Drag is the aerodynamic force that acts opposite to the direction of motion of an object moving through a fluid (such as air). It is caused by air resistance and friction as the object moves through the air.
The lift force is the force acting against the aircraft's weight. For straight and level flight, lift acts in the upward vertical direction and the weight of the aircraft acts in the downward vertical direction. For level flight, lift = weight.
Lift does not act opposite to friction. Lift opposes weight and friction(air resistance) opposes thrust from the engine. This is all equally true whether or not you happen to be aboard the aircraft.

Well, it's true that the gravitational force acting on the box acts in the direction opposite to the direction of your lifting force, but there's nothing malicious or contrary about it. In fact, the gravitational force was there before you came on the scene, and as you lined up your lift, it was you who decided to oppose it.
A rocket is able to lift off because of something called thrust. This means if you apply force to one direction, it will also apply force to the opposite direction.
Drag is a force that acts opposite to the direction of movement of an airplane. Drag is mainly caused by air. The other forces that act on the plane while moving in the air are thrust, lift etc..
A pulley is a simple machine in which the direction of effort can be opposite to the direction of resistance. By using multiple pulleys and changing the direction of the rope, you can apply force in one direction to lift a load in the opposite direction.
Lift is the aerodynamic force that helps an aircraft overcome gravity and stay airborne. Opposing forces typically refer to drag, which is the aerodynamic force that acts in the opposite direction to the aircraft's motion, slowing it down. These forces play key roles in the flight dynamics of an aircraft.
An airfoil can exert lift, drag, and thrust forces. Lift force is generated perpendicular to the airflow and is essential for providing the upward force needed for an aircraft to stay aloft. Drag force acts opposite to the direction of motion and resists the aircraft's movement. Thrust force is generated by the aircraft's engines and propels the aircraft forward.
The opposite of the verb to lift is to lower.The opposite force factor, opposing aerodynamic lift, is weight. (gravity)
