What is Mechanics? |
A branch of physics: The study of MOTIONS and of the FORCES that cause those motions |
|
|
What is Biomechanics? |
Applying the principles of mechanics to living organisms (e.g. the human body and its parts) |
|
|
Static vs. Dynamic |
Static = anything dealing with objects moving in a constant velocity or at rest Dynamic = objects in accelerated motion |
|
|
Kinematics vs. Kinetics |
Kinematics=a description of motion Kinetics= a deals with the forces that cause or creates changes in motion ---> Inertia=a resistance to action or to change (no units) |
|
|
Length, Time, Mass Units |
Length= meters (m) Time =seconds (s) Mass= kilograms (kg) |
|
|
Transverse plane- axis? |
superior-inferior axis ex) external and internal rotation |
|
|
Frontal Plane- axis? |
anterior-posterior axis ex) abduction and adduction |
|
|
Sagittal Plane -axis? |
medial-lateral axis ( to show left or right side) ex) flexion and extension |
|
|
Prone |
laying on stomach |
|
|
Supine |
laying on back |
|
|
Circumduction |
combination of flexion, extension, abduction, & adduction |
|
|
Units and Dimensions Volume Acceleration Force Work/Energy |
Volume= mxmxm=m^3 Acceleration= m/s^2 Force =kg(m/s^2)= Newtons (N) Work/Energy =Nxm = Joules(J)p |
