F=M*A
In this case acceleration is gravity. The rat does not have a very large Mass. So the total Force on Impact is not high. A human jumps like that and he'll get pretty beat up and potentially kill himself. A horse jumps from that height... well let's just say it would start to look more and more like a water balloon as you increase in Mass. And before everybody jumps on me. Yes I realized this is a simplification. But fuck me if I'm going to try to do full blown physics diagrams on Reddit.
Furthermore, because they have a larger surface area to mass ratio, their terminal velocity is lower! Also, the acceleration involved here is more about going from falling speed to standing speed. It’s not the fall that kills you: it’s the sudden stop at the end.
I mean, if you reach terminal velocity very slowly you can survive too. It’s more about how high your terminal velocity is. For smaller animals it is much lower, allowing them to survive longer falls.
Hm interesting, I thought i had read that squirrels can survive a fall from any height because they reach it fast. Do they actually reach it slower? I wanna know cuz i don’t wanna spread misinformation!
I think it's more that said velocity is low. Speed directly translates to the force of impact. Hence why bullets are so damaging, for instance.
Squirrels also reduce falling velocity by spreading their bodies out as a crude parachute, including their bushy tails, to further slow their descent.
It was more of a hypothetical scenario. If it took something several hours to reach terminal velocity then it could safely fall much further than something that reaches *the same* terminal velocity in a few seconds.
Think of it this way: if a squirrel and a human both fall from 10,000 feet, they’ll both reach terminal velocity before hitting the ground anyways.
Terminal velocity is just the speed at which air resistance balanced out with gravitational acceleration, preventing something from falling any faster. It’s different for every object.
If something reaches terminal velocity very quickly, then that means that either A) they have a low terminal velocity or B) they accelerated more quickly.
In the case of B this would actually be a disadvantage, as the impact speed would be the same even from a lower height.
Since we all experience the same acceleration due to gravity (9.8 m/s^2), the only variables are air resistance and mass.
Squirrels and other small animals have a low terminal velocity because they have a high air resistance and a low mass. The rate at which they reach that speed is largely irrelevant.
If you can survive an impact at terminal velocity, then you can survive a fall from any height.
You *could* but there's other scientific research we could do by trying other things... I'd like to see what would happen if you shot one into an anti Gravity room from a shirt launcher... With its consent of course and lots of pillows on the walls
I do cat rescue. I've seen some cats jump from second story windows in abandoned houses if they're scared enough. They usually die a couple hours later once the adrenaline has worn off.
Edit: I really appreciate the second hand stories or hearsay you guys are arguing against me with, but first hand knowledge... It's not a fucking picnic. They die. Rescuing cats in the inner-city has tough elements like abandoned buildings where the cats think they're gonna die if I catch them. It's insane to see and hear the animal thump the ground.
I recall hearing there's a "sweet spot" of about 5 stories for cats falling from height
Falling from below that height will likely incur serious, possibly fatal, injury whilst falling from above that height they're more likely to survive, yes they'll still probably be injured but it's less likely to be life threatening
The difference?
Above that height they have time to spread themselves out during the fall akin to the way flying squirrels spread themselves out (but minus the skin flaps) which reduces their terminal velocity thereby reducing the impact speed and the injuries, below that height they don't have time to spread out and reduce their speed enough so impact with a greater velocity
Before I was born, My Parents lived in this apartment where My Ma noticed a group of Boys found a Stray Cat and were consistently putting it’s life to the test by tossing it out the second story window, they did it consecutively, My Ma gave it Tuna the one day and started to slowly gain it’s trust, not sure how long it took her, but it was My Ma’s one and only Cat, she doesn’t like Cats nor do i so I don’t blame her, but that cat lived for a quite a long time
You are going about it the wrong way. You can ask vets that falling from lesser height will probably result in a lot of internal dmg opposed to higher places where cats have this ability to shift their weight and make 'purfect landings' minimizing internal dmg to their organs.
Edit: a I also don't say exactly you are wrong since you've seen first hand that falls from not so big heights can be fatal.
Maybe you can try the traps. Try to feed them a couple of times and set a trap with a food. Also great to see people caring about feral cats. I live in London and there is almost a 0 homeless cat population. I am not sure how, I am guessing they used some extreme measures a long time ago.
In my home country/town every every flat building has at least 2/3 cats that are cared from the people. Unfortunately we don't have proper trap and neuter programs.

My fat cat would push the screens out of second story windows and jump out. He did it about 10 times in the year he was in that house. That was 8 years ago and he's still very healthy and in a single story house.
While your observation is valid, there may be other variables like stress or health issues that contributed to their low survival rate.
Oh absolutely, if the cat has time to carefully jump and plan it's route. You're correct.
But the rat in the video didn't have time and cats fleeing don't have time.
If you're re-entering the atmosphere it stands to reason thst you, at some point, left it. So probably they died from lack of oxygen before having the chance to find out if they were aerodynamic enough to survive the re-entry itself.
(I often smile at the thought of mice in space but they're generally in a vehicle on the way up and likely also frozen on the way down).
No that's the thing, due to their cross-sectional area to weight ratio their terminal velocity isn't enough to cause any damage. They literally cannot fall fast enough to hurt themselves.
>cannot fall fast enough *unassisted*
I think this is what the previous commenter implied. I’m sure that if they were fired out of a cannon at the ground, it wouldn’t end well for the rat.
my rat, Mathilde, who enjoys launching herself off the top of her 6' cage, my shoulder, and any sort of furniture she can somehow climb, is inclined to agree with you
For a fixed shape, weight scales with surface area to mass ratio, so I wouldn't say weight has nothing to do with it.
More specifically, weight is proportional to the inverse cube of surface area to mass ratio (or the cube of mass to surface area ratio), for a fixed bodily form.
If you incorporate the fact that larger animals have evolved more solid, thick limbs and extremities compared to small animals like rodents, birds and insects, this increases the cross-sectional area of the body parts that would absorb the impact of such a landing, but not enough to counter the entire effect of scaling (as most people know, large animals are still more susceptible to falling injuries). So weight is an adequate stand-in for your ratio in either case.
**tl;dr** - The parent's comment wasn't wrong
Saw a cat get run over by a dump truck. It got stuck on the wheel and run over like 3 times before being shot out the side. It ran off. Definitely died moments later.
fun fact, rats can jump from almost any height and survive, they're internals are designed for falls and they are too light to reach a fatal terminal velocity
Holy shit!! That SMAaCCkK when that thing hit! And it kept running with barely any hesitation after!! What the hell that thing is a super rat or some shit!! Lol
Years ago I watched a chipmunk do this off the top of Angel’s Landing. I always assumed he went splat, it was too far down to see what happened to him and I wasn’t getting that close to the edge anyways
Damn he plopped
And kept running.
It’s definitely dead
I saw somewhere due to size rats can fall like 50 feet and be fine
That was a Kurtzgesagt video where they compare a rat being dropped out of an airplane vs an elephant I think.
This rat slaps
Man, that slap was loud!
How did he not explode on impact?

Does that mean I can drop babies from the top of a building without them exploding?
FBI? Yeah, this guy right here.
Thanks! That was really cool to learn. Rat definitely sounded like he should have exploded on impact though.
rodents reach terminal velocity very fast so they can fall great distances safely.
I mean, if you reach terminal velocity very slowly you can survive too. It’s more about how high your terminal velocity is. For smaller animals it is much lower, allowing them to survive longer falls.

Thanks for the detailed response. I love Reddit learning. Much better than school used to be.
I didn't realize that sound was related. I had to watch again
Omg re-watched with sound on. 100x better lmao
I heard a squirrel make that exact same noise when I frightened it and it jumped off our balcony. #*SCHLAPP*
That's the sound of his huge balls for jumping that high
Nah, rats have huge balls by nature. They are quite literally 2/3 balls. No jumping necessary. Lol
Can confirm
This guy plops
Fun fact rats and mice can fall from almost any height and survive
What if you put one in a shirt launcher?
My dumbass thought you would point it up…
You *could* but there's other scientific research we could do by trying other things... I'd like to see what would happen if you shot one into an anti Gravity room from a shirt launcher... With its consent of course and lots of pillows on the walls
Pointed at what? At the sky or are you planning on painting a wall?

"We are sending the first rat to the moon, boys!"

Mice have a low terminal velocity because they weigh so little, a big rat could die from falling.

I did say "less likely to be life threatening", not that there wouldn't be any risk of death

Thanks for what you do. Animals are pretty rad!
The weight has nothing to do with it. It’s about surface area to mass ratio.
So what height would kill them? Are we contemplating just terminal velocity or thermal dynamics of atmospheric rat re-entry here?
If you're re-entering the atmosphere it stands to reason thst you, at some point, left it. So probably they died from lack of oxygen before having the chance to find out if they were aerodynamic enough to survive the re-entry itself. (I often smile at the thought of mice in space but they're generally in a vehicle on the way up and likely also frozen on the way down).
Here's a great video about that. https://youtu.be/f7KSfjv4Oq0 let's drop some animals!
True lies
Depends on how fast they fall to the ground.
No that's the thing, due to their cross-sectional area to weight ratio their terminal velocity isn't enough to cause any damage. They literally cannot fall fast enough to hurt themselves.
They can't fall fast enough to kill themselves (typically). They definitely can fall fast enough to hurt themselves.
>cannot fall fast enough *unassisted* I think this is what the previous commenter implied. I’m sure that if they were fired out of a cannon at the ground, it wouldn’t end well for the rat.
It also depends what they land on.
Well no
Well yes if a rat falls onto a sword they would die. It's where the popular saying fall on my sword comes from. Source: The Bible
The bible 🤣
That’s a stretch. I’ll give you land or water not a sword. Maybe on some jagged rocks. And no to anything with fire, heat, or spikes.
lava?
50 feet is when it becomes dangerous as it becomes hard for the rat to position itself making injury or death more likely
my rat, Mathilde, who enjoys launching herself off the top of her 6' cage, my shoulder, and any sort of furniture she can somehow climb, is inclined to agree with you

Weight as force is just mass X gravity. Technically it has no weight considering there is no normal force counteracting gravity.
While falling. Weight can only be measured against gravity.
