Space cushion, created by pressure difference around an aircraft wing, generates lift, the force opposing weight. As the wing moves through the air, its curved upper surface accelerates the airflow, creating a lower pressure region above compared to the high pressure below. This pressure difference forms the space cushion, generating lift. Angle of attack, the…

Thinking distance, crucial for safe driving, is the total distance covered while perceiving and reacting to hazards on the road. It consists of perception distance, where drivers recognize the hazard, and reaction distance, where they take action (e.g., braking). Improved thinking distance allows for more reaction time, reducing collision risks. Factors affecting thinking distance include…
