Parachute Experiment

Set factors

A: Canopy shape

Round Square Hexagon

B: Material

Plastic Nylon Paper

C: Canopy diameter (cm) Range 30–90 cm

D: String length (cm) Range 20–80 cm

Drop height (m) Constant, not a factor

Experiment mode

Deterministic Stochastic

Same factors always produce the same result.

Fixed constants used in the model

Payload + parachute mass 0.12 kg.
Base Cd by shape: round 1.50, square 1.28, hexagon 1.40.
Material factor: plastic ×1.02, nylon ×1.08, paper ×0.92.
Gravity + quadratic air drag (½ρCdAv²), integrated every 0.005 s.
