Biomechanics

Definition

Biomechanics is the study of the mechanical laws relating to the movement or structure of living organisms. It combines principles from physics and engineering with biology to analyze how organisms move, develop, and function in their environments. By examining forces and their effects on biological systems, biomechanics helps to understand everything from human movement to the locomotion of animals.
