W. P. Beyermann Fall 2007 3 What is classical mechanics? • The description of “slow” motion of “macroscopic” objects. • This is important because this understanding can be used to explain much more complicated systems. (e.g., the flow of blood in arteries and the flow of current in electronic devices.)
