Free Fall Calculator
Calculate free fall time and impact velocity from height. Uses d = ½gt² and v = gt.
How to Use the Free Fall Calculator
- Enter the height from which the object falls in meters.
- Click Calculate to find the fall time and impact velocity.
- Results show velocity in both m/s and km/h.

公式
t = √(2h/g); v = g·t, where h is height (m), g ≈ 9.807 m/s², t is time (s), v is final velocity (m/s).
常见问题
Does this account for air resistance?
No, this calculator assumes free fall in a vacuum. Real-world falls are slowed by air drag.
What value of g is used?
Standard gravity g = 9.80665 m/s².
Is this calculator free?
Yes, all OhMyCalc calculators are completely free.
