11. DEFINITIONS Biomechanics - mechanics of structure & function
Mechanics - statics & dynamics
Statics - nonmoving systems
Dynamics - kinetics & kinematics
Kinetics - forces that cause movement
Kinematics - describing motion

12. Kinetics - forces friction gravity muscle pressure reaction buoyancy
centripetal
elasticity
fluid drag
fluid lift
friction
gravity
muscle
pressure
reaction

13. Kinematics- describe movement
velocity - m/sec., degrees or rads/sec. (57.3°)
acceleration - change v OR change direction
displacement - in meters or degrees / radians
momentum - M = mv (linear) OR L = I (rotary)

14. Efficient Movement minimal energy expenditure
necessary for endurance sports and repetitive tasks in labor
allows performer to endure longer
allows performer to performer faster with less energy expended

15. Effective Movement not concerned with efficiency
most appropriate movements to achieve Mechanical Purpose [MP] aka Overall Performance Objective [OPO]
most appropriate sequence of movements [e.g. large parts then small parts]
