How it works
Calculate a drop from rest without air resistance.
THE CALCULATIONtime = √(2h/g); impact speed = √(2gh)
Using this calculator
Enter drop height (m), gravity (m/s²). time = √(2h/g); impact speed = √(2gh).
What to keep in mind
An idealized educational model in the displayed SI units. Real systems may include losses and conditions not represented here. This is not a safety or engineering certification.
Frequently asked questions
Are my entries saved?
No. Calculator inputs remain in the current page and are cleared when you reload or leave. The tools do not upload your entries.
Why are results rounded?
The display is rounded for readability. Calculations use unrounded intermediate values. An estimate should not be interpreted as an exact measurement.
