PHYS 2001 Chapter : Ch07 Impulse Momentum Collisions Powerpoint
Document Summary
How do we coordinate the many muscles and joints necessary to perform a task. How do we choose between the wide variety of combinations of components available to perform a task. How do we choose order of movement segments needed to perform a task. It must accurately describe a large class of observations. A theory is build on a large number of experiments or observations which are logically related to each other. It must make definite predictions about the results of future (unobserved) observations. Predictions made by a theory can be tested. A theory can be disproved by experimental evidence. Describes and explains how the nervous system produces coordinated movement of motor skill in a variety of environments. Coordination- need to coordinate all movement segments together to make an action. The degrees of freedom problem- has to do with can we do something in a lot of different ways; have to solve this so we can chose.
