Definition and Relevance of Forces and Their Measurement
Understanding forces and their measurement is crucial in the field of biomechanics. A force is any interaction that, when unopposed, changes the motion of an object. It can be a push or a pull resulting from the object's interaction with another object. In biomechanics, studying forces allows us to analyze human movement, evaluate performance, and prevent injuries. The measurement of forces provides quantified data to support research, development, and application in fields such as sports science, rehabilitation, and ergonomics.
