Step 1: Understanding biomechanics.
Biomechanics is the study of the mechanical laws relating to the movement or structure of living organisms. It examines how internal forces (muscle contractions, joint forces) and external forces (gravity, friction) interact with the human body.
Step 2: Analyzing the options.
- (1) Kinesiology: While kinesiology is related to the study of human movement, it is broader and not specifically focused on forces.
- (2) Biomechanics: Correct. Biomechanics is the correct term that encompasses the study of both internal and external forces acting on the body.
- (3) Kinetics: This refers specifically to the study of forces in motion, but biomechanics encompasses more aspects, including structure and force application.
- (4) Kinematics: Incorrect. Kinematics is concerned with motion without considering forces.
Step 3: Conclusion.
Therefore, the correct answer is (2) Biomechanics, which deals with the forces acting on the human body and their effects.
