Biomechanics chapter 1-3 exam
Most human movement falls into which category? - Answer-General motion
is the study of the description of motion, including considerations of space and time - Answer-
kinematics
the base unit for mass in the metric system is the - Answer-kilogram
Shear - Answer-force acts parallel to a surface
which of the following defines center of gravity? - Answer-intersection of the 3 cardinal planes
the point around which a body's weight is equally balanced regardless of body position
In a free body diagram of the human body, where would the vector representing weight of the body
originate? - Answer-Center of gravity
a person balancing motionless on one foot is an example of a _____ situation - Answer-static
, a bending force can result in which two types of stress? - Answer-compression & tension
True/False weight is always a force, so force is always a weight - Answer-false
Dynamics - Answer-is a branch of mechanics dealing with systems subject to acceleration
Posterior - Answer-means toward the back of the body
frontal - Answer-plane in which lateral movements of the body and body segments occur.
Possible detrimental effects of knee braces include(s) which of the following?
A. changes muscle activity during gait
B. reduces sprinting speed
C. increases onset of fatigue
D. all of the above - Answer-all of the above
force - Answer-can be thought of as a push or a pull acting on a body.
Rectilinear - Answer-is a movement along a straight like
Distal - Answer-means further from the trunk
true/false: stress is measured/calculated the same as Pressure - Answer-True
True/false: promising work in the development of intervention strategies has shown that the key to
preventing falls may be the ability to limit trunk motion - Answer-true
