Free Fall Calculator

Free fall is the motion of an object falling solely under gravity, with no air resistance. Near Earth's surface, all objects accelerate at g = 9.81 m/s² regardless of mass — a fact Galileo demonstrated and Einstein explained through general relativity.

Fun Fact

On the Moon (g=1.62 m/s²), the same 45m drop would take 7.45 seconds. This is why the Apollo astronauts could hammer golf balls and they seemed to float down so slowly.
