Horizontal Projectile Motion Calculator

Find the flight time and range of a horizontally launched projectile.

Launch height

Horizontal speed

Gravity (m/s²)

Time to land 1.428

Horizontal range 11.423

Formula: t = √(2h/g); range = v₀·t

Step-by-step with your numbers:

1. Values used:

2. Launch height = 10

3. Horizontal speed = 8

4. Gravity = 9.81 m/s²

6. Time to land = 1.428

7. Horizontal range = 11.423

Did we solve your problem today?

When launched horizontally, a projectile's fall time depends only on its height.

The math behind it

Vertical: t = √(2h/g). Horizontal range = v₀·t, since horizontal speed stays constant.

Height 10 m, speed 8 m/s → falls in 1.43 s, lands 11.4 m away.

Does horizontal speed change the fall time?

No — vertical and horizontal motion are independent.
