IB Physics HL A 2 3 Free Body Diagrams Questions

Practise analysing HL free-body diagrams for coupled systems, buoyancy, orbital motion, drag, tension and changing force conditions.

Exam points

Construct a free-body diagram that isolates the chosen body and labels every external force with correct direction and point of action.
Use a complete free-body diagram to resolve forces and determine the resultant or equilibrium condition from mark-scheme evidence.
