Measurement and physical models.

Physics begins by defining a system, measuring it and stating limits.

Learning outcome: Build a units-aware model and separate observation from assumption.

Core ideas

Build the model

SI units and dimensions.

uncertainty, repeatability and bias.

system boundaries and idealization.

Engineering bridge

Where it is used

measurement and an engineering notebook
simulation and model verification

Original Lilerno structure and wording. Visuals are conceptual, inputs are not a design specification, and practical work requires appropriate supervision.
