: Examines the forces—such as muscle force, gravity, and friction—that produce or result from motion. Biomechanics | Science | Research Starters - EBSCO
: Focuses on the description of motion without considering the forces that cause it. This includes analyzing position, velocity, and acceleration of body segments. Basic Biomechanics
The field is traditionally divided into two primary sub-disciplines that describe motion and the causes behind it: : Examines the forces—such as muscle force, gravity,
