A wing's camber is the curvature of the airfoil, which significantly influences the pressure distribution over the wing surfaces when the aircraft is in flight. The shape of the camber affects how air flows over and under the wing, resulting in differences in airspeed and pressure on the upper and lower surfaces.

When the camber of a wing is increased, it can enhance the lift produced. This is because the airflow over the upper surface accelerates, leading to lower pressure according to Bernoulli's principle. Simultaneously, the airflow beneath the wing remains relatively slower, creating higher pressure. The difference in pressure between the upper and lower surfaces results in an upward lift force. Therefore, the camber directly contributes to the wing's ability to generate lift by creating this pressure differential.

Understanding camber is crucial for aerodynamics because it allows for more efficient wing design, enabling aircraft to achieve the needed lift at various speeds and angles of attack. This highlights the importance of camber in wing design for effective flight performance.
