Learning objective
Investigate how launch speed and angle control range, flight time and maximum height.
Investigation procedure
- Set speed to 24 m/s and angle to 30°. Predict the landing range.
- Run the simulation and compare the calculated and observed range.
- Repeat for 45° and 60° without changing speed. What symmetry appears?
Observation and reasoning
1. At a fixed launch speed, what angle maximizes the level-ground range?
2. Do complementary launch angles give the same range?
3. What happens to the range if speed doubles?
Teacher answer key
1. 45°, because sin(2θ) reaches its maximum value of 1.
2. Yes, θ and (90° − θ) give the same sin(2θ), provided launch and landing height are equal and air resistance is absent.
3. Range increases by a factor of four at fixed angle and g (R ∝ v₀²).
