Projectile with Drag

How this simulation works

Use the Launch Speed slider to set how fast the projectile leaves the ground (in m/s) and the Launch Angle slider to set its direction above horizontal (in degrees). Use the Drag Coefficient slider to control air resistance — set it to zero for a perfect parabola, or increase it to see drag shorten the range and flatten the peak. Press Start to fire the projectile, Pause to freeze it mid-flight, and Reset to clear the trail and start over. Comparing launches at the same speed and angle with different drag values makes the effect of air resistance immediately visible.
