Kinesiology: Biomechanics Flashcards
1
Q
Kinematics
A
- Description of motion without considering forces
- Time, acceleration, velocity, position
2
Q
Kinetics
A
- Description of moving bodies and the forces that produce motion
- connects motion to the forces that create them
3
Q
Statics
A
The study of forces acting on a body in equilibrium
- No Acceleration (constant velocity)
- F=ma
4
Q
Dynamics
A
The study of forces acting on a body not in equilibrium
-Acceleration (unbalanced forces)
5
Q
Arthrology
A
Study of the joints of the body
6
Q
Articulation
A
-the union of adjacent bones, whether they enjoy movement or not
7
Q
Osteokinematics
A
Direction of movement of the distal segment of the joint
8
Q
Arthrokinematics
A
Direction of movement of articular joint surfaces
- Roll, spin, slide/glide
- movement inside the joint
9
Q
Anatomic Body Position
A
- Standing erect with feet together
- Looking forward
- Arms held at side
- Elbows extended
- Forearms supinated
- wrist and fingers neutral
10
Q
Planes
A
-Frontal Plane, Sagittal Plane, Transverse Plane
11
Q
Axes
A
Anteroposterior Axis, Coronal Axis, Longitudinal Axis
12
Q
Rule of three
A
- segment, moving on a segment, moving on a joint
13
Q
Vector
A
-magnitude & direction
14
Q
Angular motion
A
- movement of an object around a fixed axis
- all points move at an equal angular velocity
- all points move at an unequal linear velocity
