Free Fall Calculator — science and physics formula calculators
The Free Fall Calculator determines how long an object takes to fall from a given height and how fast it is moving at the moment of impact, assuming it starts from rest and ignoring air resistance. It works for any object dropped straight down, from a dropped tool to a released stone. Use it to esti

About this tool
What Is Free Fall Calculator? Free Fall Calculator is a browser-based tool for Calculate fall time and impact speed from height and gravity. This guide explains the result, the calculation or processing method, and correct usage. Calculation or Processing Method Enter height and local gravity, then review time and speed. Real objects may differ because of drag and rotation. Formula or method: For rest-to-fall motion, t = √(2h/g) and impact speed v = √(2gh), ignoring air resistance. How to Use It Open the tool and choose the required unit, mode, or options. Enter values or paste text into the input fields. Review the result, copy it, or continue with a related tool. Important Notes Use consistent units and verify values before calculating. Incomplete or invalid input can produce an incomplete result.
