IB Physics HL A.2.19 Newton’s second law forms
Strengthen force analysis by resolving vectors, choosing axes carefully, and applying Newton's second law in standard and momentum forms.
How this is tested
- resolve a force into components on a free-body diagram, then apply ΣF = ma along one axis
- use F = Δp/Δt for changing-mass or drag cases, with clear units for force and momentum rate
- choose the accelerating component correctly, checking weight, angle choice, and sign convention
