Calculating your distance fallen is straightforward once you know the Free Fall Distance formula and what each input means. This guide explains the method in plain language, walks through a manual calculation, and gives worked examples you can follow — then you can do it instantly with the Free Fall Distance Calculator.
What is Free Fall Distance?
The Free Fall Distance calculation tells you your distance fallen from a few simple inputs. The figure you are solving for here is the distance fallen.
The Free Fall Distance formula
The core formula is:
Distance fallen = 0.5 × Gravity × Fall time ^ 2Here is what each input means:
- Fall time — a value measured in s. Example: 3 s.
- Gravity — a value measured in m/s². Example: 9.81 m/s².
How to calculate it step by step
- Write down the fall time (for example, 3 s).
- Write down the gravity (for example, 9.81 m/s²).
- Apply the formula above to get your distance fallen.
- Double-check the result with the Free Fall Distance Calculator.
Worked examples
Example 1
| Input / Output | Value |
|---|---|
| Fall time | 3 s |
| Gravity | 9.81 m/s² |
| Distance fallen | 44.1450 |
With fall time of 3 s and gravity of 9.81 m/s², the distance fallen works out to 44.1450.
Example 2
With fall time of 6 s and gravity of 9.81 m/s², the distance fallen works out to 176.5800.
| Result | Value |
|---|---|
| Distance fallen | 176.5800 |
Example 3
With fall time of 1.5 s and gravity of 9.81 m/s², the distance fallen works out to 11.0363.
| Result | Value |
|---|---|
| Distance fallen | 11.0363 |
Tips for an accurate result
- Keep your units consistent — mixing, say, months with years or grams with kilograms is the most common source of error.
- Round only at the very end. Rounding inputs early can shift the final answer noticeably.
- Re-run the numbers whenever an input changes, rather than estimating from an old result.
