Lesson 1
The study of the structure and function of biological systems by means of the methods of mechanics
biomechanics
Rate of change in location
Displacement
A quantity that has only magnitude
Scalar
airborne body that is subjected to only gravity & wind resistance after it has left the ground
Projectile
Initial contact from one step of one foot till the initial contact of the other foot
Step
mechanics that result in injury
mechanopathology
Total distance an object/body travels
Distance
A quantity that has both magnitude and direction
Vector
a smooth, flat space defined by two perpendicular axes
Plane
defined as # of steps in a given time frame
Cadence
the mechanics that are a result of an injury
pathomechanics
quantity of velocity at a given moment in time
Instantaneous velocity
magnitude of the value regardless of the sign (- OR +)
Absolute
the sum of two or more vectors
Resultant
Initial contact from one foot until the initial contact of the same foot
Stride
study of forces of motion
kinetics
The process of adjusting one variable for the influence of another variable or variables
Normalization
Movement to the left direction from the origin of a coordinate system produces which kind of motion
Negative
parts of a resultant vector, two or more vectors that are acting in different directions
Components
study of description of motion, including considerations of space and time
Kinematics
These 3 sets principles are used in biomechanics
multisegment, biological & mechanical
What a two ways in which to improve gait speed
Increasing Stride Length and Rate
During a change of direction task, which kinematic variable is more important in determining the outcome of the race, velocity or acceleration
Acceleration
What is the main difference between distance and displacement
Displacement considers final position relative to starting position
Which variable has the greatest impact on trajectory
Projection Velocity
