Motion in a Gravitational Field: projectiles, energy and drag
Use one uniform gravitational-field model consistently across force, component-motion and energy descriptions, then identify how drag changes the motion.
Before you begin
Study each reviewed objective cluster, then use the recorded diagnostic and repair plan. H2 practice evidence remains separate from H1 and H3.

Course coverage and review details
The official topic combines material currently taught through the Kinematics, Projectile Motion, Energy & Fields, and Drag Force resources; the three groups keep those outcome boundaries explicit.
Coverage is reviewed against 9478 topic 5(a)–(e), PDF page 15. Selected-response progress does not by itself prove constructed, diagrammatic or practical performance.
