Pretty sure when I started physics in high school we started with measuring trolleys accelerating (or not) done an inclined run timed with ticker tape and covered the maths alongside the experiments.
Edit: I seem to remember friction being addressed pretty quickly as it was required to explain why your trolley would stop accelerating.... [NB It's been 30+ years]
