scientific study of human movement

Question 4

biomechanics

Answer 4

the study of the structure and function of biological systems by means of the methods of mechanics

Question 5

Linear motion

Answer 5

movement (straight or curved) pathway where all the points on a (body or object) move the same distance in the same amount of time

Question 6

angular motion

Answer 6

motion around (some point) so that different regions of the same (body segment or object) do not move through the same distance in a given amount of time

Question 7

Kinematics

Answer 7

concerned with the characteristics of motion from a spatial and temporal perspective without reference to the forces causing the motion

Question 8

Kinetics

Answer 8

area of study that examines the forces acting on a system

Question 9

Statics

Answer 9

branch of mechanics that examines systems that are not moving or are moving at a constant speed

Question 10

Dynamics

Answer 10

branch of mechanics used to evaluate systems that are being accelerated

ipsilateral

Answer 14

same side

Question 16

absolute reference frame

Answer 16

is one in which the axes intersect at the center of the joint and movement of a segment is described with respect to that joint

Question 17

relative reference frame

Answer 17

is one in which the movement of a segment is described relative to the adjacent segment
