Document Summary
Biomechanics is the mechanical principles that directly relate to the body. Static deals with aspects of non moving or virtually non moving systems. Focuses on dynamic body one that changes shape at an appreciable rate ahd how various forces affect it. Arthrokinematics: less considered, focuses on the motion that occurs between the articulating surfaces of joints. Kinetics: studies forces (gravity, friction, and pressure) that act on the body to generate or alter motion. Kinematics: analysis of movement in terms of mechanical elements (time, space, mass) Force: any influence that causes an object to undergo a certain change. Forces either affect your tissues from the outside of your body or emanate from inside of your body. Inertia: object"s resistance to a change in its state of motion or rest. Mass: quantity of matter in an object. More mass in an object, the greater it resists changes. Torque: force that involves a rotation of an object about (around) an axis.
