Biomechanics: Exam 1 (Chapter 1-2)
what is biomechanics - Answer-the physics (mechanics) of motion produced by biological systems.
biomechanics more specifically - Answer-a highly integrated field of study that examines the forces
acting upon, within, and produced by a body.
biomechanics - Answer-integrates biological characteristics with traditional mechanics.
Mechanics - Answer-the branch of physics specifically concerned with the effect of forces and energy on
the motion of bodies.
types of mechanics - Answer-statics
dynamics
statics - Answer--study of systems in a state of equilibrium.
-at rest or in a constant state of motion.
dynamics - Answer-the study of systems in a state of accelerated/changing motion.
, Biomechanical Analyses - Answer-Kinetics
Kinematics
Kinetics - Answer-study of forces that inhibit, cause, facilitate, or modify motion of a body.
-example: friction, gravity, and pressure.
Kinematics - Answer-study of description of the spatial and temporal characteristics of motion without
regard to the causative forces.
-example: displacement and velocity
Biomechanical Analyses - Answer--often associated with sports
-example: a soccer player injures a knee while trying to outmaneuver an opponent.
kinematic perspective - Answer-how fast was the soccer player moving at the moment of injury?
kinetic perspective - Answer-how much force was absorbed by the body when making a quick change in
direction?
outside of sport, biomechanists also examine - Answer-more common human motions such as walking.
Example: walking infant
Kinematic perspective: What is the length of the infant's strides?
Kinetic perspective: Why does the infant walk in this manner?
Biomechanics is about movement: - Answer-Exercise Physiology
