|---|---|---|---|---|---|
| Line Drive | 92 | 18 | 3.0 | 2 | 0.33 |

Formula Used
vx = v cos(θ), vy = v sin(θ)
A = π(d / 2)2
Fd = 0.5 ρ Cd A vrel2
vrel,x = vx − vwind, vrel,y = vy
ax = −(Fd / m)(vrel,x / vrel)
ay = −g − (Fd / m)(vrel,y / vrel)
v = v + aΔt, x = x + vxΔt, y = y + vyΔt
This model tracks a two-dimensional baseball path with gravity, headwind or tailwind, and drag. It does not include sideways break or spin-driven lift.

Frequently Asked Questions
1. What does this calculator estimate?
It estimates a baseball’s two-dimensional flight path. The tool returns distance, hang time, peak height, landing speed, landing angle, and a plotted trajectory using drag and wind inputs.
2. Why does drag matter for baseball flight?
Drag slows the ball throughout the flight. Higher drag reduces carry distance, lowers the apex, and shortens hang time compared with an ideal no-drag projectile model.
3. What wind direction should I enter?
Use positive wind for a tailwind that pushes the ball forward. Use negative wind for a headwind that increases resistance and usually reduces travel distance.
4. Why is the no-drag range also shown?
The no-drag value provides a clean reference. It shows how far the ball would travel without air resistance, helping you see the real effect of aerodynamic losses.
5. How accurate is the result?
The result is useful for planning and comparison. Real baseball flight also depends on seam effects, spin-driven lift, weather variability, and measurement quality.
6. What time step should I use?
A smaller time step improves numerical smoothness but increases calculations. Values near 0.01 seconds usually work well for baseball trajectories and responsive page performance.
7. Can I use this for softball or training balls?
Yes. Change mass, diameter, drag coefficient, and speed inputs to match the ball. The same calculation structure can compare different ball types or practice conditions.
8. Why does launch height change the range?
A higher release point gives the ball more time before landing. That extra time can increase horizontal distance, especially when the ball already has strong forward speed.
