1.Matter and Energy
For each chapter we cover, I prepare a page with practice problems, study guides, useful links, etc. as relevant. The practice problems are marked either:
​
Fundamental: start on these early in content coverage
or
​
Challenge: do these later to prove to yourself you're close to mastering a topic.
​
I will also update the page on occasion as we work through the material. Check back often!

This will give you a sense of scale and orders of magnitude in length in the known universe. Note the scientific notation on the bottom right.
Problems: Unit Conversion, Dimensional Analysis, and Order of Magnitude

a. It’s 66 miles from downtown New Haven to JFK airport. What’s that in kilometers? How many orders of magnitude larger is that larger than the length of a Yale dorm room?
b. What’s that in kilometers?
c. How many orders of magnitude larger is that larger than the length of a Yale dorm room?
