Impact dynamics refers to the study of how forces interact during collisions or impacts. This field examines the behavior of objects when they collide, including the transfer of energy and momentum. Understanding these interactions is crucial in various applications, such as vehicle safety design and sports equipment development. In impact dynamics, factors like speed, mass, and material properties play significant roles in determining the outcome of a collision. Researchers often use mathematical models and simulations to predict the effects of impacts, which can help improve safety measures in industries like automotive and aerospace.
