Document Summary

Lecture 1- september 9 ** not on the midterm. Kinematics: is it changing speeds, getting faster or slower- describing motion. Kinematics: velocity- m/sec, degrees or rads/sec, acceleration change the velocity of change the direction, displacement- in meters or degrees/radians, momentum (m= mv (linear) or (l= lw (rotary) Efficient movement: minimal energy expenditure, necessary for endurance sports and repetitive tsk in labor, allows performer to endure longer, allows performer to preform faster with less energy expenditure. Effective movement: not concerns with efficiency, most appropriate movement to achieve mechanical purpose (mp) aka overall performance objective (opo, appropriate sequence of movement large muscle to small muscles. Muscles and bones can act as levers, and also the wheel axel do not need to know the. Thorax 12 x 2 ribs + sternum. Vertebral column: cervical 7 bones, thoracic 12 bones, lumbar 5 bones. Upper extremities: shoulders to carpals 32 x 2 right and left.
