Definitions
The term for an anatomical landmark closer to the attachment of a limb to the body.
What is proximal?
The axis that runs horizontally front to back and perpendicular to the frontal plane
What is the anteroposterior axis?
force/area
What is pressure?
A body at rest will remain at rest, and a body in motion will remain in motion in a straight line
What is Newton's First Law?
The study of forces that inhibit, cause, facilitate, or modify motion of a body.
What is kinetics?
The plane in which rotation occurs
change in velocity/change in time
What is acceleration?
Every action force is met with an equal and opposite reaction force
A system’s quantity of motion
What is momentum?
The anterior and posterior mass halves of the body
What is the frontal plane?
force x moment arm
What is torque?
In the absence of a net externally applied force, the total momentum of a system that comprises multiple bodies remains constant in time
What is the principle of conservation of linear momentum?
Two or more vectors are summed to determine a single resultant vector
What is vector composition?
A plane that passes directly through the midline of the body, dividing the mass in half
What is a cardinal plane?
work/change in time
What is power?
A body submerged in a fluid will be buoyed up by a force that is equal in magnitude to the weight of the displaced water
Archimedes principle
The quality of a material whose deformation is affected by both the rate of loading and the length of time it is subjected to a constant load
What is viscoelastic?
The planes of motion involved in the motion of the shoulder
All three
F/A/change in length/length initially
What is Young's Modulus
If loading on a particular bone increases, the bone will remodel itself over time to become stronger to resist that sort of loading.
What is Wolff's Law?
