1. The problem statement, all variables and given/known data We have two animals. One of them is as big as an elephant or it's an elephant and the other one is a small animal as a cat. When we drop them from a high place, the smaller animal hurts less compared to the bigger one. Why? 2. Relevant equations Surface area / volume 3. The attempt at a solution I am not really sure. But maybe it can be something about durability(Cross-sectional area/volume). Or the smaller one hurts less because he has a less surface area so when it hits the ground it recieves less force compared to other. I am not so sure that's why I'm asking P.S. This is my first time on the forums and I am not a native speaker. So there can be some wrong usage of the words. But I hope you understand what I mean. In this unit we are learning how to calculate durability of the objects like cubes, spheres etc. Thank you for your understanding.
