Calculate ideal free fall online

From rest: time = √(2h/g); impact speed = √(2gh). Use this to calculate a stated mathematical relationship from your own explicit assumptions. Units and input order are part of the calculation; no changing external rates or laws are inferred.

How to use it

Enter 2 comma-separated numbers in this order: drop height metres, gravity m/s². Choose Calculate. Review the output, then copy or download it.

Worked examples

Use this to calculate a stated mathematical relationship from your own explicit assumptions. Units and input order are part of the calculation; no changing external rates or laws are inferred.

Reproducible worked example

Settings: No additional settings.

Input:

10, 9.80665

With the input and settings above, the tool produces:

Output:

{
  "seconds": 1.4280869812290344,
  "speedMetresPerSecond": 14.00474919446971
}

For this input, “seconds” is 1.4280869812290344; “speedMetresPerSecond” is 14.00474919446971. These are the named fields in the example output.

Limitations and common mistakes

  • Ideal model without air resistance or intermediate contact.
  • Combined input is bounded to 150,000 characters; output text is bounded to 1.2 million characters. Some algorithms impose smaller limits, stated in their error messages.
  • Use a dot as the decimal separator and commas or spaces between numeric entries. The calculation uses floating-point arithmetic unless exact integers are explicitly stated.
