Terminal Velocity Calculator
Maximum falling speed with air resistance
Terminal Velocity Calculator turns maximum falling speed with air resistance into an instant, step-by-step result. Just enter Mass (kg), Air Density (kg/m³) and Drag Coefficient (Cd) and the result updates as you type. You get a clean, precise output with the full working shown, so you can verify every step. Everything runs in your browser — your inputs are not sent to our servers, and it works offline after the first visit (currency conversion needs a live connection). Searching for terminal velocity calculator drag falling object or free online terminal velocity calculator? This tool covers it — free, fast, and private. Open Terminal Velocity Calculator, enter your numbers, and you will have a trustworthy answer before you know it.
What does the Terminal Velocity Calculator do?
Terminal Velocity Calculator works out the maximum falling speed from the Mass, Air Density, and Drag Coefficient, following standard Science conventions — the page defaults produce a maximum falling speed of Terminal velocity = 47.83 m/s.
- Inputs: Mass, Air Density, and Drag Coefficient.
- Output: the maximum falling speed, plus the intermediate steps behind it.
- Method: the standard Science formula, evaluated entirely in your browser.
Quick answer
With the default inputs (mass of 80, air density of 1.225, drag coefficient of 0.7), terminal velocity calculator returns a maximum falling speed of Terminal velocity = 47.83 m/s. Assumptions and limits are summarized below.
How does it work?
Terminal Velocity Calculator computes the maximum falling speed directly from your inputs — the Mass, Air Density, and Drag Coefficient feed the formula. Nothing is uploaded: the math runs locally in your browser and the result appears as you type.
How the Terminal Velocity Calculator works
At its core, Terminal Velocity Calculator takes the Mass, Air Density, and Drag Coefficient and evaluates the standard formula step by step, so the maximum falling speed can be checked rather than trusted on faith.
How to use it
- Mass — in terminal velocity calculator, this value feeds the formula directly, and the steps panel shows exactly where it enters the maximum falling speed.
- Air Density — one of the values the calculation builds from; the result reflects exactly what you type here.
- Drag Coefficient — used in the first stage of the calculation, so entering it accurately matters more than any later refinement.
- Review the output. Beyond the headline maximum falling speed, the intermediate steps are listed — useful for catching a mistyped input.
- Iterate. Vary the inputs one at a time; the movement in the figure shows which lever matters most for your terminal velocity question.
The formula behind the result
Terminal Velocity Calculator lists every intermediate step in the result panel, so the derivation of the figure can be checked line by line.
Worked example: with mass of 80, air density of 1.225, drag coefficient of 0.7, this terminal velocity calculation returns Terminal velocity = 47.83 m/s. The same run reports = 172.2 km/h | v = √(2mg / ρACd).
The steps it follows:
- Formula: v = √(2mg / ρACd)
- 2mg = 2 × 80 × 9.81 = 1569.60
- ρACd = 1.225 × 0.8 × 0.7 = 0.686
- v = √(1569.60 / 0.686) = 47.83 m/s
Substitute your own values and the same steps produce your answer — that is the point of a calculator that shows its working.
Understanding the result
Interpret the maximum falling speed against the inputs that produced it — the same number from different inputs can mean different things, which is why the pairing is always shown.
Where it helps
Typical uses for Terminal Velocity Calculator include planning around a target figure, comparing scenarios side by side, and double-checking the maximum falling speed — anywhere the figure needs to be defensible rather than guessed.
Common mistakes
The most common error with Terminal Velocity Calculator is a unit mismatch — one value entered in different units than its label assumes quietly skews the output. Check each label before typing.
Tip: If the maximum falling speed looks wrong, read the steps panel before re-entering anything; it usually shows exactly where the number departed from expectation.
Assumptions and limitations
The model behind Terminal Velocity Calculator covers the standard case; special cases, edge values, or jurisdiction-specific rules may need manual adjustment.
Why use this calculator
Because the page doubles as documentation: Terminal Velocity Calculator puts the formula, a worked example, and the assumptions right beside the calculator.

Frequently Asked Questions
What does the Terminal Velocity Calculator calculate?
Terminal Velocity Calculator keeps the whole calculation in front of you — the Mass, Air Density, and Drag Coefficient, the formula, the intermediate steps, and a worked example you can reproduce line by line. Because the working is visible: Terminal Velocity Calculator shows each operation behind the figure in the steps panel, so you can verify the result instead of trusting a black box.
How is the maximum falling speed calculated?
The first steps are formula: v = √(2mg / ρacd), then 2mg = 2 × 80 × 9.81 = 1569.60. The calculation in Terminal Velocity Calculator applies the standard Science method, keeping full precision internally and rounding only the final display.
What do I need to use the Terminal Velocity Calculator?
The Mass, Air Density, and Drag Coefficient it asks for, or the page defaults if you just want to see the calculation work. Each input maps directly to the formula, and changing any one of them recalculates the maximum falling speed instantly.
What does the result from the Terminal Velocity Calculator mean?
The main number the terminal velocity calculator returns is the maximum falling speed for your exact inputs, and the supporting figures and step list give it context. Results from Terminal Velocity Calculator are estimates computed from the values entered; real-world outcomes can differ when fees, taxes, or conditions not modeled here apply.
When is the Terminal Velocity Calculator most useful?
Common scenarios for Terminal Velocity Calculator: planning around a target figure, comparing scenarios side by side, and double-checking the maximum falling speed. The step list makes it equally useful for learning the method and for double-checking someone else's numbers. Run Terminal Velocity Calculator twice with deliberately low and high inputs; the spread tells you how sensitive the maximum falling speed is, which a single run never shows.
