Frequently Asked Questions
What is the formula for free fall?
From rest, height h = ½gt², time t = √(2h/g), and impact velocity v = gt, with g = 9.81 m/s².
Does air resistance matter?
Yes for long falls or light objects - this calculator ignores it (vacuum model). Real impact speeds cap at terminal velocity.
What if the object is thrown down?
Then it has an initial velocity v₀ ≠ 0. Use the acceleration calculator instead and treat g as the acceleration.
