Biomechanics is the study of the mechanical aspects of biological systems, ranging from whole organisms to organs, cells, and cell organelles, using the methods of mechanics. It is a branch of biophysics that involves the analysis of the mechanics of human movement. Biomechanics is traditionally divided into the areas of kinematics and kinetics. Kinematics is the study of motion without considering the forces that cause the motion, while kinetics is the study of the forces that cause motion. Biomechanics is applied in various fields, including sports, exercise, rehabilitation, and injury prevention. Biomechanics is also used to study the mechanical properties of soft tissue and bones, and to investigate the movement and development of limbs. Biomechanics is a combination of the Greek words "bios" meaning life and "mēchanikē" meaning mechanics. Biomechanics can be studied using both qualitative and quantitative approaches. Qualitative analysis involves observing and describing human movement, while quantitative analysis involves measuring and analyzing human movement using mathematical and statistical methods.
