You just watched a squirrel miss the branch and fall three stories.
You gasped.
The squirrel hit the ground, bounced once, and kept running.
It wasn't lucky. It was physics.
A squirrel can fall from any height and survive. Any height. A tree. A building. A plane. It doesn't matter.
THE PHYSICS:
→ Terminal velocity is the maximum speed an object reaches in freefall
→ For a human: 120 mph. Fatal.
→ For a squirrel: 23 mph. Not fatal.
→ At 23 mph, a squirrel's body can absorb the impact without lethal injury
→ This is because of the ratio of body mass to surface area
WHY 23 MPH:
→ A squirrel weighs 1-1.5 pounds
→ Its bushy tail + spread legs create a large surface area relative to its weight
→ More surface area = more air resistance = slower fall speed
→ The squirrel essentially becomes its own parachute
→ They instinctively spread all four legs and flatten their body in freefall
THE TAIL:
→ It's not just for balance — it's an airfoil
→ The tail increases drag by 10%
→ In a fall, the tail acts as a stabilizer, keeping the squirrel belly-down
→ Belly-down = maximum air resistance = slowest possible terminal velocity
→ Cats do this too (righting reflex), but they're heavier so their terminal velocity is higher
WHAT THIS MEANS:
→ A squirrel falling from 100 feet hits the ground at the same speed as one falling from 1,000 feet
→ Both survive
→ This is why squirrels jump between branches with zero hesitation
→ They don't fear heights because heights can't kill them
→ The most reckless animal in your yard is also the most physics-proof
That squirrel didn't get lucky.
It's literally unkillable by gravity.
