Required depth: Connect the chosen reference point with rates and changing motion. Use algebra, trigonometry and graphs; numerical projectiles use constant near-surface gravity with negligible drag.

Study this section → The reference-point explanation and signed-position model were read.

Study this section → Distance/time and displacement/time are distinguished.

Study this section → The signed velocity-change model supplies the third quantity.

Still needed: No separate objective-specific canonical practice item was verified.

No practice question has yet been verified for this objective.

Required depth: Explain each rate and identify the corresponding graph gradient. Use algebra, trigonometry and graphs; numerical projectiles use constant near-surface gravity with negligible drag.

Study this section → The two definitions are stated with units.

Study this section → Average acceleration is explicitly defined.

Study this section → The graph connects its slope with acceleration.

Still needed: No separate objective-specific canonical practice item was verified.

Required depth: Determine both kinds of rate, rather than merely name them. Use algebra, trigonometry and graphs; numerical projectiles use constant near-surface gravity with negligible drag.

Study this section → The speedometer note distinguishes a moment from an interval.

Study this section → Piecewise position-time samples support interval slopes.

Study this section → The implemented calculation is an average.

Still needed: Add numerical tangent constructions and instantaneous-acceleration examples; the current lessons mainly calculate interval averages. No separate objective-specific canonical practice item was verified.

No practice question has yet been verified for this objective.

Required depth: Choose a suitable equation, preserve signs and check the constant-acceleration model. Use algebra, trigonometry and graphs; numerical projectiles use constant near-surface gravity with negligible drag.

Study this section → All four formula choices and their use conditions are available.

Practise this objective →

Required depth: Explain when acceleration stays fixed and interpret a changing-rate case. Use algebra, trigonometry and graphs; numerical projectiles use constant near-surface gravity with negligible drag.

Study this section → The constant-acceleration condition is explicit.

Study this section → Motion graphs introduce changing motion but do not complete a variable-acceleration treatment.

Still needed: Add a worked non-uniform-acceleration graph and explain why the constant-acceleration equations then fail. No separate objective-specific canonical practice item was verified.

No practice question has yet been verified for this objective.

Required depth: Apply the model to horizontal launches and launches on either side of the horizontal. Use algebra, trigonometry and graphs; numerical projectiles use constant near-surface gravity with negligible drag.

Study this section → The component and trajectory models cover upward-angle and horizontal examples.

Still needed: The main angle control starts at +10 degrees and the separate case is horizontal; no downward-angled worked launch was verified.

Practise this objective →

Required depth: Explain changes to trajectory, flight timing and limiting motion qualitatively. Use algebra, trigonometry and graphs; numerical projectiles use constant near-surface gravity with negligible drag.

Study this section → The model boundary states that drag opposes velocity and changes both components.

Still needed: Add a coherent flight-with-drag explanation, including terminal speed; the current teaching boundary is only a short warning.
