# The higher the bigger the drop

Cat in free fall (1st image – assumption of falling from the first floor of a building; 2nd image – assumption of falling from the third floor of a building)

If a cat falls from the first floor of a building, will it have more or less physical problems than if it falls from the third?

Aerodynamics teaches us that the lighter the body, the slower it falls.

This is the case with our cat friend. We noticed a free fall of the animal, which leads us to analyze this event as a vertical launch downwards, that is, a uniformly accelerated rectilinear movement, in which the speed of the falling body increases over time.

We cannot forget that in the fall there is also air resistance, which will allow the cat to succeed in its fall or not (this success depends on the height).

Analyzing the physical phenomena already presented, we observed that the cat, when falling from the first floor, will not have enough time to succeed in the fall, because the fall time does not allow the kitty to have the ideal posture capable of “defending it”.

When he falls from the third floor, a moment of limiting velocity occurs, in which the air resistance increases until the moment in which it equals the weight of the animal’s body, a fact that cancels the resulting acceleration, causing the cat to fall. with constant speed, having time to achieve a complete posture, thus avoiding possible shock damage.

Conclusion: based on the laws of aerodynamics, we can conclude that the risks of falling from the 20th or 90th floor of a skyscraper are equal.
