Kinematics of Human Motion Flashcards
1
Q
Define biomechanics
A
Biomechanics is the application of mechanics to the study of living system
2
Q
Categories of mechanics; Explain each
A
Kinematics
- >defining movement without reference to the forces that cause the movement
Kinetics
- > an analysis of the forces that cause movement
Energetics
- > applying concepts of work, energy and power to human movement
3
Q
List some examples of standard units of kinematic measures
A
Time (seconds)
Displacement (m)
Velocity (m/s)
Acceleration (m/s2)
4
Q
Why do we use angular kinematics; what are the different angular kinematic mesurements
A
- > this is how people move
Time
Angular Displacement (degrees or radians)
Angular velocity (degrees or radians / seconds)
Angular acceleration (degrees or radians / s2)
5
Q
How do I find average angular velocity
A
6
Q
How do we convert distance in pixels
A
sqrt( deltaX2 + deltaY2)
- > x and y are detemined through imputing linked segment modeling
