the centre of rotation. For a system to be in complete balance both force and couple polygons should be closed. ------------------------------------------------- Static balance Static balance occurs when the centre of gravity of an object is on the axis of rotation. The object can therefore remain stationary, with the axis horizontal, without the application of any braking force. It has no tendency to rotate due to the force of gravity. ------------------------------------------------- Dynamic

Force Applied vs Distance for a Spring Statement of Problem: To graphically and mathematically model the relationship between force applied and distance stretched for a spring. Hypothesis: If the weight increases then the distance will also increase because of the amount of force applied will cause the blue spring to extend down. Experimental design: Materials: Meter stick/Ruler, Clip to hold ruler, Blue Spring, and multiple weights Independent Variable: Amount of weight used in (g)

identifying, analyzing, and solving problems related to the biomechanics of human movement. Definition of Biomechanics The term biomechanics combines the prefix bio, meaning “life,” with the field of mechanics, which is the study of the actions of forces. The international community of scientists adopted the term biomechanics during the early 1970s to describe the science involving the study of the mechanical aspects of living organisms. Within the fields of kinesiology and exercise science, the living
