Document Summary
Identify the forces acting on the human body. Levers (long bones) being accelerated about the axes (joints) Internal and external forces and their effect on the body. Allow analysis of movement: quality o quantity. Requires an understanding of both: structure and function. 4 types of motion caused by the application of force: no displacement (stationary, linear displacement, rotational (angular) displacement, displacement- to stationary, no displacement (stationary) Centre of mass must be over base of support. What is your centre of mass (centre of gravity: the point around which the body"s mass is equally distributed in all directions, centre of mass changes as your body shape does. Balance: process whereby the body"s state of equilibrium is controlled for a given purpose. Equilibrium: state of a system that is not experiencing any change in direction or speed (rest or constant velocity) Linear motion result when the forces are applied through the com.
