Which field is the study of mechanical laws relating to movement?

• A. Biomechanics
• B. Kinesiology
• C. Physiology
• D. Ergonomics

Answer: (A)

Mechanical laws govern motion, and biomechanics is the field that investigates how living bodies move by applying physics to anatomy and movement. It looks at forces, torques, and moments acting on limbs to explain how joints and muscles produce motion, why a runner’s foot interacts with the ground in a certain way, or how leverage changes during different poses.

Kinesiology covers human movement more broadly, including physiological and psychological aspects, but it isn’t limited to the mechanical laws of movement. Physiology focuses on how body systems function and energy use, not the mechanics of motion. Ergonomics centers on designing tools, equipment, and workplaces to fit human movement and reduce risk, which often uses biomechanics but is about design and safety rather than the fundamental mechanical laws of movement.
