Learning Paths
Each learning path is one chapter: a guided route through a topic, one small course at a time. Pick a class to see its chapters in order.
Chapter 1
Units and Measurement
Every law of physics is a statement about numbers that we measure. How long is a table, how heavy is a bag, how long does a swing take? A number alone means nothing, so we write it with a unit, and no measurement is ever exact, so we also say how far we can trust it. In this chapter we learn the SI units, how to read an instrument, how to write an answer with the right number of digits, and how the dimensions of a quantity can check an equation. Python helps us calculate, simulate and test.
