Calculate range, max height, and flight time of a projectile given initial velocity and launch angle.
Projectile Motion Equations
| Quantity | Formula |
|---|
| Horizontal velocity | Vx = V·cos(θ) |
| Vertical velocity | Vy = V·sin(θ) |
| Max height | H = h + Vy²/(2g) |
| Flight time | t = (Vy + √(Vy²+2gh))/g |
| Range | R = Vx × t |
Maximum range occurs at 45° (from ground level with no air resistance).
How to Use This Projectile Motion Calculator
Enter the initial velocity, launch angle, and initial height. The calculator shows maximum height, range, flight time, and trajectory path.
Formula & How It Works
Range = v₀² × sin(2θ) / g. Max Height = v₀² × sin²(θ) / (2g). Flight Time = 2 × v₀ × sin(θ) / g. g = 9.8 m/s².
Calculation Example
Ball launched at 20 m/s at 45°: Range = 40.8 m, Max Height = 10.2 m, Flight Time = 2.88 s. 45° gives maximum range on flat ground.
Expert Tips
45° launch angle gives maximum range (on level ground). In reality, air resistance significantly reduces range. For different launch/landing heights, use the quadratic formula for flight time.
