Why Ants Survive Falls: Terminal Velocity Explained
A typical forest ant has a terminal velocity of only 6.4 kilometers per hour due to its high surface-area-to-weight ratio. Because this speed is so low, an ant can fall from the Empire State Building and walk away completely unharmed.

artiteacher Terminal Velocity
Drag meets weight / speed stays straight / terminal velocity!
artiteacher Flying squirrels and geckos use skin membranes to survive massive falls.
Fun Fact
Ant survival: Ants can survive falls from any height because their tiny size limits their terminal velocity to a gentle 6.4 kilometers per hour.
artiteacher A belly-to-earth skydiver reaches a terminal velocity of about 120 mph.
Glossary
terminal velocity (noun)
The constant maximum speed achieved by a falling object when the resistance of the medium prevents further acceleration. In 2012, Felix Baumgartner reached a record speed of 843.6 miles per hour falling from the stratosphere.
