Mekanik refers to the branch of physics and engineering that deals with the behavior of physical bodies when subjected to forces or displacements. It encompasses various concepts such as motion, energy, and the forces acting on objects. Mekanik is essential in understanding how machines and structures operate, making it a fundamental aspect of mechanical engineering. In practical applications, mekanik is used in designing vehicles, buildings, and machinery. It involves principles from classical mechanics, which include Newton's laws of motion and kinematics. By applying these principles, engineers can predict how objects will move and interact, ensuring safety and efficiency in their designs.
