1. Kin 151: Biomechanics Test 1 Review
Chapter 1,2: Introduction to biomechanics:
Kinesiology: the study of movement
Biomechanics: A branch of physics, applies the principle of mechanics to living
organisms
Biomechanics can be used to solve qualitative and quantitative problems
Professions that utilize biomechanics
oTherapists – measure linear kinematics during therapy, individuals perform
exercise’s emphasizing form, therapists look for a return to ‘normal’ joint
kinematics
oCoaches – use kinematics for teaching movements, trying to modify athletes
technique and use a change in kinematics to measure technique
Biomechanics may be a useful tool for sport educators, teachers,
coaches, athletic trainers, physical therapists, and others involved in
human movement
Definitions
Linear: along a line that may be straight or curved with all parts of the body moving in
the same direction at same speed
Angular: Involving rotation around a central line or point
General: involving translation and rotation simultaneously
Kinematics: The study of the description of motion, including considerations of space
and time
Kinetics: The study of the action of forces
Static State: Constant state of motion , moving at same rate without acceleration
Dynamic State: System is subject to acceleration, velocity is changing
Chapter 10: Linear Kinematic Concepts
Definitions
Distance: The amount of space between two points  Total length of travel
Speed: Measurement of how fast you’re going  the rate of motion
Velocity: The speed of a system in a given direction
