Physics in Context · Part 1 of 2
6 exam-style questions with model answers, plus 8 quick multi-choice questions — every question on this part of the standard, grouped by the 2 pages of notes they come from.
Write a full answer before you reveal the model one. That comparison is where the learning happens.
State the physics concept most relevant to explaining why a car's crumple zone reduces injury in a crash, and describe that concept.
Explain how or why a crumple zone reduces the force on the occupants of a car in a collision.
Discuss why modern cars combine a crumple zone with a rigid passenger cell, linking at least two physics concepts and justifying why both features are needed.
For the context of a guitar string, state two physics concepts that apply, and describe one of them.
Explain why pressing a guitar string against a fret raises the pitch of the note produced.
Discuss how the design of a guitar produces notes of different pitch and loudness, integrating at least two physics concepts and using a calculation with realistic values.
