Calculator guide

Understanding Projectile Scenario Comparison Calculator

Two projectile launches can share height and gravity yet differ substantially in range, flight time, apex, and target clearance because speed and angle affect different velocity components. This comparison solves both paths independently before calculating any difference.

Independent solves A and B never share derived values.
Same axes The overlay uses one metre scale.
Target line Both margins reference the same distance.
Components explain outcomes Angle redistributes speed between axes.

Calculation method

How the calculation works

Solve two independent ideal projectile scenarios under the same gravity and height before comparing range, time, apex, and target-distance margins. Both paths share one origin and gravity, making the signed range difference directly comparable. Apply the component and positive-impact equations separately to scenarios A and B, then subtract their ranges and compare each range with the entered target distance.

Detailed calculation process

Solve two projectile paths before comparing their target margins

Scenario A uses 28 m/s at 35°, scenario B uses 32 m/s at 45°, and both start at 1.2 m under standard gravity.

General formula: for i in {A,B}: v_xi = v_i cos(theta_i)v_yi = v_i sin(theta_i)t_i = [v_yi + sqrt(v_yi^2 + 2gh_0)]/gR_i = v_xi t_iH_i = h_0 + v_yi^2/(2g)DeltaR = R_B - R_A Each scenario must first produce its own component velocities, flight time, range, and apex. Only then are ranges and target margins subtracted, preventing one scenario's time or angle from leaking into the other.

What each symbol means

v_A, v_B Scenario launch speeds (m/s).
theta_A, theta_B Scenario launch angles (degrees).
h_0, g Shared launch height (m) and gravity (m/s²).
t_A, t_B Positive flight times (s).
R_A, R_B Horizontal ranges (m).
H_A, H_B Maximum heights (m).
DeltaR, D B-minus-A range difference and entered target distance (m).

Worked substitution with the default inputs

1. Resolve scenario A v_xA = 28 cos(35°) = 22.9363 m/sv_yA = 28 sin(35°) = 16.0601 m/s Scenario A retains more horizontal than vertical speed.
2. Complete scenario A t_A = 3.34845 sR_A = 22.9363(3.34845) = 76.8008 mH_A = 14.3507 m The positive impact root and horizontal component determine A's full path.
3. Resolve and complete scenario B v_xB = 32 cos(45°) = 22.6274 m/sv_yB = 22.6274 m/st_B = 4.66715 sR_B = 105.6055 mH_B = 27.3047 m B has similar horizontal speed but substantially greater vertical speed and flight time.
4. Compare ranges DeltaR = 105.6055 - 76.8008 = 28.8047 m The reported difference is B minus A, so a positive result favors B's modeled range.
5. Check the 70 m target M_A = 76.8008 - 70 = 6.8008 mM_B = 105.6055 - 70 = 35.6055 m Both reach the entered target distance, but their remaining range margins are kept separate.

Under the defaults, B travels 28.805 m farther, stays aloft 1.319 s longer, and peaks 12.954 m higher than A.

Scenario comparison

Overlay both ideal trajectories on one coordinate plane

Two function curves show where speed and angle alter range and apex while a shared target line anchors the comparison.

Path A The 28 m/s, 35° trajectory.
Path B The 32 m/s, 45° trajectory.
Target distance One vertical reference for both ranges.
Apex labels Each peak remains separately identified.

Worked situations

Practical examples

  • A reaches 76.801 m while B reaches 105.605 m.
  • Both scenarios clear the 70 m range target.
  • B's higher vertical component produces a much higher apex.

Better inputs

Useful tips

  • Change one scenario input at a time when testing sensitivity.
  • Compare components as well as final range.
  • Use identical environmental assumptions for a fair ideal comparison.

Before relying on the result

Limitations and common mistakes

  • Both scenarios exclude aerodynamic effects and assume point masses.
  • The same gravity and launch height are imposed on both paths.
  • A longer ideal range does not establish real-world accuracy or safety.

Reference

Key terms

Scenario margin
Modeled range minus the entered target distance.

Frequently asked questions

Why can horizontal velocities be similar but ranges differ?

Flight time also matters; B's larger vertical component keeps it aloft longer.

Is 45° always the longest-range angle?

Only under restricted ideal assumptions, especially zero launch height and no drag.

What does a negative target margin mean?

The modeled range ends before the entered target distance.

Are the two paths evaluated independently?

Yes. Each uses its own speed and angle.
