When an aircraft is pulling up, what forces are primarily acting upon it?

When an aircraft is pulling up, the primary forces acting upon it are weight and lift.

As the aircraft maneuvers to climb, it generates lift to overcome its weight. Lift is produced by the wings as air flows over them, creating an upward force that counteracts the downward pull of gravity, which is the aircraft's weight. For the aircraft to successfully pull up and gain altitude, the lift must be greater than the weight at that moment.

Weight continuously pulls the aircraft downward, while lift is crucial for maintaining altitude or climbing. Thus, the presence of both weight and lift is essential in this scenario, as they directly influence the aircraft's ability to change altitude. Understanding these forces is fundamental to aviation operations and directly relates to the performance and stability of the aircraft in flight.
