University Physics Volume 1

A physical model links measured quantities to predictions that can fail.

How to study this source

• How do observations constrain a physical model?

  coreSections 1.1–1.4; focus on units, models and uncertainty before equations

  A physical model links measured quantities to predictions that can fail.

• How can we distinguish position from velocity?

  coreChapter 3, Motion Along a Straight Line; first sections

  Velocity describes change in position over time; it is not the position itself.

• How do constraints shape an engineered design?

  coreChapter 12, Static Equilibrium and Elasticity; conceptual examples

  A design can only be evaluated against a goal, constraints and a way to measure performance.

• What can a prototype test establish?

  coreChapter 12 conceptual examples; use forces and constraints to state the test conditions

  A test answers a defined question under stated conditions.
