Measure carefully before modelling. This chapter builds uncertainty, scale, instruments, and physical quantities.
Start chapter Next: KinematicsStudy two or three interactives, then answer the concept checks before moving on.

Study two or three interactives, then answer the concept checks before moving on.
If this chapter feels hard, study the first few interactives and use the concept checks until your streak improves. If it feels easy, jump to resources with videos or OSPSG links and explain the model evidence in your own words.

Use the x-y graph to add data points, adjust a polynomial curve, compare with Best Fit, and judge whether the model fits the data using residuals or visible mismatch.
