OhMyCalc

Projectile Motion Calculator

Calculate range, max height, and flight time for projectile motion. Enter launch velocity and angle.

How to Use the Projectile Motion Calculator

  1. Enter the initial launch velocity in m/s.
  2. Enter the launch angle in degrees (0–90).
  3. Click Calculate to see range, maximum height, and total flight time.

使用例

計算式

Range = v²·sin(2θ)/g; Max height = v²·sin²(θ)/(2g); Flight time = 2v·sin(θ)/g. Assumes flat ground, no air resistance.

よくある質問

What angle gives maximum range?
45° gives the maximum range on flat ground when air resistance is neglected.
Does air resistance affect real projectiles?
Yes, air resistance reduces range and max height. This calculator gives the ideal (vacuum) result.
Is this calculator free?
Yes, all OhMyCalc calculators are completely free.
