Kinetics #1
Tendency of a body to maintain its current state of motion, whether motionless or moving with a constant velocity
Inertia
Pressure
Force that tends to shorten or squeeze something, decreasing its volume
Compression
The rate of change in velocity of an object or the human body.
Acceleration
________ focuses on the mechanics of injury and the principles of prevention, evaluation, and treatment of musculoskeletal problems.
Clinical Biomechanics
Quantity of matter contained in an object
Mass
Amount of space occupied by a three-dimensional object or region of space
Volume
Force that tends to stretch or elongate something
Tensile/Tension
Occurs when the external force causes a change in the shape or structure of an object or body component.
Deformation
_________ is the study of the interaction between humans, the objects they use, and the environments in which they function
Ergonomics
Something that causes a change in the motion of a body
Force
Measure of the quantity of some physical property expressed as mass per unit volume
Density
Force acting on a substance in a direction perpendicular to the extension of the substance
Shear
The _________ and _______ of the force and the area over which the force is distributed are important factors in determining the potential for tissue injury.
magnitude/direction
The examination of factors of human movement associated with exercise training and sport for the purpose of improving performance and preventing injury
Sport Biomechanics
Point around which the body's weight is equally balanced, no matter how the body is positioned
Center of gravity
Tendency of a force applied to an object to make the object rotate about an axis
Torque

Improving an athlete’s _________ is one of the most common methods for enhancing performance in sport and athletic competition
technique
Force with which an object is attracted toward the center of the earth by gravity
Weight
Change of momentum of a body or physical system over a time interval; equal to the force applied times the length of the time interval over which it is applied
Impulse
