Apparent Weight in Elevators: AP Physics Guided Notes
A guided-notes packet for AP Physics that walks students through apparent weight and scale readings during elevator up and down acceleration. Students fill in blanks on true weight, the sign convention, and Newton's second law as they build toward free body diagrams and scale calculations.

Teacher Guide & Tips
- Use as a 30 to 45 minute mini-lesson or independent note-taking block before students solve elevator scale problems.
- Discussion question: Why does the scale read more than your true weight when an elevator accelerates upward, even though your mass has not changed?
- Scaffold for struggling readers: Pair them with a partner to draw the two forces (weight down, normal force up) before filling in the blanks, and review the sign convention box together first.
- Extension for advanced students: Ask them to derive the scale reading for an elevator in free fall and for a cable snap, and explain why the scale reads zero in those cases.
- Estimated time: about 35 minutes including discussion.
