Impact absorption refers to the ability of a material or structure to reduce the force of an impact. This is crucial in various applications, such as in the design of helmets, car bumpers, and sports equipment. When an object collides with another, impact absorption materials help to dissipate the energy, minimizing damage and protecting the people involved. Different materials have varying levels of impact absorption. For instance, foam is commonly used in protective gear because it compresses upon impact, spreading the force over a larger area. Similarly, rubber is often used in shoes to cushion the feet during activities, providing comfort and reducing the risk of injury.
