Main Question or Discussion Point

I am confused that many web sites say that it took 25 N to crack the egg, it's ok but

When I do the drop test with 8 meter building. So, I calculate the force: 1kg(box) * 9.81m/s^2

So, the force tat impact my box is 9.81 Newton but the egg was crack. I just confuse!

You dropped a box? Try dropping a single egg. How much does a single egg weigh? I never used them so take it 'x', w=mg
=9.8x
They say 25N no? well
25=9.8x
x=25/9.8
=2.55
an egg can't be 2.55 kg right?
At what height did they drop the egg?
momentum=mass*velocity.
when you drop the egg from great height, by the time it reaches the earth, the velocity increases much and hence momentum. And hence it experiences much force. U must consider the height.
