Method and calculation
A release from rest gives time sqrt(2h/g) and impact speed sqrt(2gh).
Inputs and settings
Free Fall Calculator accepts Drop height (m) (minimum 0); Gravity (m/s²) (minimum 0.000001).
Worked example

Free Fall Calculator FAQs
Free Fall Calculator applies the following rule to your input: A release from rest gives time sqrt(2h/g) and impact speed sqrt(2gh). The worked example on this page uses the same processor as the result button.
Free Fall Calculator has these boundaries: Ignores air resistance and assumes constant gravity. Start by checking the drop height (m) field against the units or format shown.
Free Fall Calculator provides this sample: { "seconds": 2.0196199771025523, "speedMetresPerSecond": 19.80570624845274 }. Use the sample button to reproduce it, then replace the inputs with your own values.
