Everything that moves can be described. This unit builds the vocabulary, the graphs, and the equations that make that possible — then puts them to work, twice, before you're on your own.
The Path Through Unit 1
You get a target position-time graph. Your job: walk in front of the sensor and reproduce it exactly. Simple to explain, surprisingly hard to do — and that gap is the whole point.
You're handed real velocity data from a bike ride, a drive, or a rollercoaster clip. Calculate how far it actually went, how hard it accelerated, and where it would end up next — the exact moves the Problem is about to ask you to make on your own.
The district wants a crosswalk near a blind curve by the gym. Given reaction-time and stopping-distance data, you decide where it should go and what the speed limit should be — and defend it in a one-page memo to the district.
