What are the free fall formulas?

Distance: d = v₀t + ½gt². Velocity: v = v₀ + gt. Time from height: t = √(2h/g) when v₀ = 0. These assume no air resistance.

How fast does a falling object go?

After 1 second: 9.8 m/s (22 mph). After 2 seconds: 19.6 m/s (44 mph). After 3 seconds: 29.4 m/s (66 mph). Terminal velocity for a human is about 53 m/s (120 mph).
