Newton’s Second Law of Motion
Written by Desmond on March 29, 2006 – 2:18 am -Few days ago, few of my friends and I were arguing about an interesting topic. I started this topic, I told them a theory….
I told them that, a person who jump out from a building from the 5th floor will have the same impact if the same person jump out from the same building from 10th floor.
Considering only the situation while landing ground and position landed on the ground that are the same. Pure landing impact and accelerate, other factors are not under consideration, impact from both floors are the same… but in the end, we ended up with a big argued. My friends say that a person from the 10th floor will have a bigger impact which means the damage for the person will be highier…
Today, here… I want to prove to you all… why is it the same…
According to the Newton’s Second Law of Motion (I’m sure ppl that study physic before are fimiliar with this) the formula for counting Force is F = ma.
As you all can see above, Accelerate is calculate by weight and newton ONLY which means HEIGHT is never a consideration!
Therefore, 5th floor = 10th floor! So, a person jumping out from 1st floor or 50th floor will have an equal accelerate (provided the landing position and situation on the way landing ground are the same…)!!!
Any argument still??

ok i agreed that the speed is that same but we were saying that the impact is different when 2 same weighted things drop from different heights. The impact is different.
