Free Fall Time from 500 meters - How Long to Fall?
Dropping an object from a height of 500 meters in vacuum results in an elapsed fall time of 10.098 seconds and a terminal impact speed of 99.03 m/s (approx. 356.5 km/h or 221.5 mph).
Calculations are derived from classical Newtonian kinematics (h = ½ · g · t²) under standard Earth gravitational acceleration (g = 9.80665 m/s²).

Frequently Asked Questions
Q1.How long does it take an object to fall 500 meters on Earth?
In a vacuum under standard Earth gravity (g = 9.80665 m/s²), an object dropped from rest takes exactly 10.098 seconds to fall 500 meters, calculated via t = √(2h / g).
Q2.What is the impact velocity from a 500m drop?
At ground impact after falling 500m, the object reaches a velocity of 99.03 m/s, which equals 356.5 km/h (221.5 mph).
Q3.How does free fall from 500m compare on the Moon vs Jupiter?
On the Moon (g = 1.62 m/s²), falling 500m takes 24.85 seconds. On Jupiter (g = 24.79 m/s²), the same fall takes just 6.35 seconds due to its immense gravitational acceleration.
