Projectile Game
Description
This projectile motion game is a problem-solving tool for physics students and teachers presenting kinematics. Rather than adjusting the cannon by trial and error, players measure the target’s position, apply the appropriate projectile motion equation, and fire a single calculated shot. Four levels introduce a new physical condition in turn – level ground, an obstacle, an elevated launch point, and an elevated target – so each one requires a different equation rather than a repetition of the last.
Components
The simulation includes:
- An adjustable cannon: set the launch angle (0°–90°) and initial speed (15–30 m/s) using the steppers, or drag the barrel and the velocity arrow directly
- Draggable measurement markers with live Δx and Δy readouts in meters
- Selectable visual aids: trajectory path, launch angle arc, initial velocity vector, and the velocity components vx, vy and v shown on the projectile in flight
- A formulas panel giving the kinematic equations, the trajectory equation, the coordinates of the highest point, and the range formula
- A guided tutorial that demonstrates every control and visual aid step by step
- Four levels: a ground target; a target behind a wall; an elevated cannon whose height changes on every shot; and an elevated standing target
Learning Outcomes
Each level isolates a different assumption. Level 1 uses the symmetric range formula and reveals that two complementary angles reach the same target. Level 2 adds a wall at the midpoint, so players must derive a minimum launch angle – and discover that clearing it depends on the angle alone, not the speed. Level 3 raises the cannon, breaking the symmetry of the range formula and requiring the general form. Level 4 places the target above the ground, so the shot must pass through a point rather than land at a distance, and the full trajectory equation is needed.
Scoring
Each level gives 10 shots, and 8 hits are needed to advance. A hit scores 10 points, with a 5-point bonus for consecutive hits.
