PMADS

Projectile Motion & Drag Simulation

1
Select independent variables - toggle on at least 3 of the 4 launch parameters using the switches. Set their values with the sliders.
2
Configure drag & density - choose a preset object or enter custom mass, drag coefficient, and cross-sectional area. Select a fluid density preset or enter a custom value.
3
Click Run - the simulator produces a trajectory graph, energy analysis at 3 key points, and all computed results including distance, peak height, time of flight, and final velocity.
4
Optional - Variable inference - toggle off one launch parameter and select a dependent variable to have the simulator solve for the unknown.
Launch Parameters
Initial Velocity 10.0 m/s
Initial Height 0.0 m
Launch Angle 45 °
Ambient Gravity 9.81 m/s²
Custom Drag
Custom Density
Variable Inference beta ?Solves for one unknown launch variable (velocity, height, angle, or gravity) given a known outcome (distance, peak height, time, or final velocity). Uses iterative simulation, converging to 0.1% relative uncertainty.
