define biomechanics in the broadest sense :
biomechanics is the study of the mechanical aspects of living organisms and their movement
what are some examples of where biomechanics can be applied ?
- sport science
- rehabilitation and physical therapy
- orthopaedics
- ergonomics
- medical research
- robotics
- occupational biomechanics
and more
what is biomechanics ?
application of mechanical principles in the study of living organisms
what does bio mean ?
biological system
what does mechanics mean ?
analysis of the actions of force
some examples of bio mechanics :
- skill improvement
- injury mechanism
- tapping/bracing/protection
- rehabilitation prescription
TRUE OR FALSE
several types of biomechanics analyses can be performed
TRUE
what are three examples of biomechanics analyses ?
- quantitative & qualitative
- statics & dynamics
- kinematics & kinetic
what are the two sub-branches of biomechanics ?
qualitative and quantitative
define qualitative :
non-numeric description or evaluation of movement based on observation (not using numbers)
define quantitative :
numeric description or evaluation of movement based on data collected during performance (using numbers)
between qualitative and quantitative which is the one known as “too expensive” ?
quantitative
what are the five branches of mechanics within biomechanics analysis ?
- rigid-body mechanics
- deformable-body mechanics
- fluid mechanics
- relativistic mechanics
- quantum mechanics
what are statistics ?
mechanics of objects moving at constant velocity
what are dynamics ?
mechanics of objects in accelerated motion (instantly changing direction and velocity)
what two branches is rigid body mechanics divided into ?
statics and dynamics
between statics and dynamics which is only kinetics ?
statics
between statics and dynamics which is kinetics and kinematics ?
dynamics
TRUE OR FALSE
kinematics and kinetics are sub-branches of biomechanics
TRUE
what are kinematics ?
- appearance or description of motion (describes time and space)
- linear kinematics
- angular kinematics
what are kinetics ?
- forces that cause motion
- linear kinetics
- angular kinetics
differentiate between kinetics and kinematics ?
kinematics is about the motion itself (position, velocity, acceleration), while kinetics is about the forces that drive or resist that motion
what are the goals of sports biomechanics ?
- technique improvement
- equipment improvement
- training improvement
- injury prevention and rehabilitation
