Aerodynamic refers to the way air moves around objects, particularly when they are in motion. It is a key concept in fields like aerospace engineering and automotive design, where understanding airflow can improve performance and efficiency. Objects designed with aerodynamic principles in mind can reduce drag, allowing them to move faster and use less energy. In nature, many animals, such as birds and fish, exhibit aerodynamic shapes that help them glide or swim efficiently through air and water. These shapes minimize resistance, enabling them to conserve energy while traveling. Engineers often study these natural designs to create more efficient vehicles and structures.
