Introductory Mechanics Core

Physical Models, Systems, and Frames

Choose a system, frame, coordinates, and particle or rigid-body idealization and state where the model fails.

Units, Dimensions, and Estimation

Convert SI quantities, reject dimensionally impossible relations, and estimate a physical scale.

Requires: Physical Models, Systems, and Frames

Measurement and Model Testing

Define repeatable measurements, distinguish resolution, scatter, and bias, and design a fair model test.

Requires: Units, Dimensions, and Estimation

Significant Figures and Reporting Measurements

Identify significant figures, distinguish exact factors, and report calculation results using stated rounding conventions.

Requires: Measurement and Model Testing

Uncertainty Bounds and Comparing Results

Interpret justified measurement intervals, calculate bounds for positive ratios, and compare measured results with predictions.
