Physics 30 - Dec 7

Today in class we started into a new topic - the theory of special relativity.  This is an advanced topic explained by Albert Einstein that has some really neat consequences.  One of those consequences is called time dilation, or the fact the when you move faster, time actually moves slower for you.  We went through what this means and how to actually calculate the time difference.  This was all covered on slides 23-46 in the Unit 4 Notes powerpoint. We did Example 8 and students were given time to do example 9.  Students were then told to begin working on Part 1 of Assignment 4.3 which is on time dilation.  Tomorrow we will start looking at another neat consequence - length contraction.
