KIN 355 Exam 2 || with Accurate Answers 100%.
Angular kinematics correct answers Study of rotational motion
Angular motion correct answers Occurs about an axis of rotation
Concentric actions correct answers -Muscle shortening under tension
-Raise the body or objects
-Try to speed up body segments or objects
-Ex: upward part of bicep curl
Eccentric actions correct answers -Muscle lengthening under tension
-Lower the body or objects
-Try to slow down body segments or object
-Ex: lowering part of bicep curl
Radian correct answers -Unitless measure of angles
-SI unit for angular measurement
-1 radian is the angular distance covered when the arc length equals the radius
Joint angles correct answers -Relative angles
-Angle between longitudinal axes of two adjacent segments
The hip, knee, and ankle angles are which type of angles? correct answers Joint (relative) angles
Segment angles correct answers -Absolute angles
-Angle between a segment and the horizontal axis
The trunk, thigh, calf, and foot angles are which type of angles? correct answers Segment angles
Are flexion values and slopes positive or negative? correct answers Positive
Are extension values and slopes positive or negative? correct answers Negative
Angular distance correct answers Length of the angular path taken
