That makes more sense. The way your post was worded it seemed to me you were trying to suggest that it's terminal velocity was low (ala the string experiment) and therefore it would die easily.

FWIW, I agree that it seems likely that there is no height you can drop a cockroach from that will kill it... although dropping it from a great height into a volcano should do the trick.

even if I tried the string experiment I would still need to let go of the string when i reach the 45 degree angle right?

And I dont really understand the terminal velocity, doesnt gravity pull at it every second it is falling, then how come there can be a terminal velocity wouldn't he just fall faster and faster?

because there is a force that is countering gravity

Air resistance grows with speed, and at a certain (terminal) velocity, the force of gravity is negated by the air resistance so the cockroach stops accelerating.

grafity exerts a contant downward force on an object, but air exerts an upward force on a falling object (called drag). the faster the object falls, the greater the drag. at some speed, the force of the drag equals the force of gravity and the falling object can accelerate no more. this speed is called terminial velocity and is slower for lighter objects (other things equal).

If you dropped a cockroach off the empire state building, assuming he couldnt fly to safety, yes, it would die. The impact from the fall out crush its body.

i'm guessing the same is true for an ant.

how wrong you are!

So like humans would have a terminal velocity as well then? So like all ppl who sky dive fall at around the same speed because they all reach their terminal velocity?

Then bugs are like indesructible if they can fall from such large distances

yes, around 120mph. read the wiki article.

and you can change it by changing your body's orientation.

ever wonder why we're not severely hurt by raindrops?
