How to use the Free Fall Velocity Calculator

The Free Fall Velocity Calculator works out your velocity at time t in an instant. Enter fall time and gravity and the result updates as you type — it is free, needs no sign-up, and runs entirely in your browser so your figures stay private.

  1. Enter the fall time.
  2. Enter the gravity.
  3. Read off your velocity at time t — the calculator updates automatically, with no button to press.

Formula

The Free Fall Velocity Calculator uses the formula:

Velocity at time t = Gravity × Fall time

Worked example

For example, with fall time of 3 s and gravity of 9.81 m/s², the velocity at time t is 29.4300.

Inputs used
Fall time 3 s
Gravity 9.81 m/s²
Results
Velocity at time t 29.4300

Results are estimates for educational use, not professional advice.

Key terms explained

Velocity
The speed of an object in a given direction.

Frequently asked questions

Use v = g × t. After 3 seconds on Earth, the speed is about 29.4 m/s.

No. Without air resistance, all objects speed up at the same rate.

In real air, drag eventually balances gravity and the object stops accelerating; this formula ignores that.

Use d = ½gt² for distance, alongside v = gt for speed.

The Free Fall Velocity Calculator uses the formula: Velocity at time t = Gravity × Fall time. For example, with fall time of 3 s and gravity of 9.81 m/s², the velocity at time t is 29.4300.
