What is the upward force that allows an aircraft to rise in the air called?

The upward force that enables an aircraft to rise in the air is known as lift. Lift is generated primarily by the aircraft's wings as they interact with the airflow. When an aircraft moves forward, air flows over and under the wings, creating a difference in pressure due to the wing's shape and angle of attack. This pressure difference produces the lift force, allowing the aircraft to overcome its weight and ascend into the air. Understanding lift is crucial for pilots and those involved in aviation, as it directly impacts the aircraft's performance during various stages of flight, including takeoff and climbing.
