IB Physics SL A 2 3 Free Body Diagrams Questions

Practise drawing isolated-body force diagrams with correctly labelled and directed forces for equilibrium, slopes, circular motion and falling objects.

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.

A cylindrical cork of height H and cross-sectional area A is floating stationary in water. Its depth below the water surface is D.

Figure for Question IB Physics SL A 2 3 Free Body Diagrams Questions question 1 — IB Physics SL

Draw and label the forces acting on the cork.

Weight and Buoyancy drawn in proper directions (by eye) and correctly identified

Allow any sensible identification of the forces (e.g. mg for $F_{g}$ )

Do not allow "gravity" for weight.
