If you describe a movement in terms of the distance covered (how far a joint rotates in flexion for example or how far someone runs) or how fast the rotation occurs or person runs you are describing a)_______________ but if you describe the muscles used and the force generated you are describing the b)_____________ of the movement.
a) kinematics and b) kinetics
Planar motion includes:
Both translation and rotation
—(like the femur/knee joint in a soccer kick)
T/F: Walking is both translatory and rotatory.
True
T/F: The motion occurring at the axis of a rotating object = 0.
True
The description of the motion inside of a joint @ the joint surfaces is called

If the convex ended bone moves at a joint surface into flexion/extension the rule states that it (the convex ended bone) moves in (same/opposite) directions of rotation and slide/glide
Opposite
If the concave ended bone moves at a joint surface into flexion/extension the rule states that it (the concave ended bone) moves in the (same/opposite) directions
Same
The loose packed postion of a joint :
1) is when the ligaments/capsule are loose
2) Is the position in which the joint mobilization typically occurs
The deformation of tissue under constant / long term load is called:
Creep
