Intro
Use of principles of mechanics, both static and dynamic, to understand the structure and function of the human body.
What is Biomechanics?
The two types of this motion are curvilinear and rectilinear.
What is linear motion?
The ratio of the circumference of a circle to its radius.
What is a radian?
If a person kicks a ball off the ground and it lands back on ground that is the same height, this is the path of motion that it followed.
What is a parabola?
The path of motion an object travels.
What is distance?
Famous as an artist but his work was mostly in engineering and muscle modeling.
Who is Leonardo da Vinci?
The change in velocity with respect to time.
What is acceleration?
The point about which a body rotates during angular motion.
What is the axis of rotation?
As velocity of impact increases, this decreases.
What is impact time?
These variables have both magnitude and direction.
What are vector variables?
Considered the father of sports medicine and served as the surgeon to the gladiators.
Who is Galen?
If direction of motion is described as something other than +/- then this is what is happening to an object that is experiencing negative acceleration.
What is slowing down?
What is 2∏ (6.28) radians?
Separation velocity divided by approach velocity.
What is the coefficient of restitution?
Mechanics of objects at rest OR moving at a constant velocity.
What is statics?
He developed the first force platform and high speed camera.
Who is Jules Marey?
The SI unit for linear acceleration.
What are meters/second2?
The component of angular acceleration that is the restraining force that pulls an object in toward its axis of rotation.
What is radial acceleration?
Horizontal velocity and relative projection height are the factors that influence this variable.
What is horizontal displacement?
The SI unit for angular velocity?
What are radians/sec or degrees/sec?
Largely disputed Galen's work and realized there were anatomical differences between humans and animals.
Who is Andreas Vesalius?
When all points on a body or object move in a straight line so the direction of motion does not change
What is rectilinear?
The component of angular acceleration that represents change in linear speed of a ball while in a pitchers hand.
What is tangential acceleration?
The optimal take off angle range for a long jumper.
What 18-27 degrees?
The angle between the femur and the tibia.
What is a joint/relative angle?
