It's early on a Saturday morning -- and after a stressful work week I woke up wondering why ships don't sink. So here I am, I need to know!

Gravity doesn't push. It pulls.
Gravity pulls it down.
Buoyancy pushes it up.

"Why Don't Big Ships Sink?"

A big ship cant sink on sea and i'm struggling to float in a pool.

[leonfisher]

So it all comes down to the balance between how heavy you are and how much displacement you produce.
I LOVE THIS GUY.

I always knew that big ships floated due to water displacement, but I never really understood the concept. Thanks!

[theTRAILdriver]

I actually work with this. there is a lot more than this going on before a ship floats. there are several dozens of pages of calculations, ballast location onboard, GZ graphs and other calculations that explain this.
This is not wrong, but this is far from a proper explanation

He should have said something about the boat weighing less than the volume of the water. A ship packed with iron balls would go straight to the bottom on the sea.

I had to watch this for homework. "If your hull cracks, that's why water seeps in." Congratulations Sherlock.

Unlike Titanic, most big ships will capsize instead of sinking and they don't break in 2 pieces

[cheyang]

Thank you bro, you just answered what's been bugging in my mind why ships don't sink even tough they are so heavy and big.

[calvinnotklein]

Ships do displace water but they are way denser than water. Even if they are denser than water, it still floats. Why? Because it displaces way more water and since it's displacing so much water, the ship will weigh less than the water that was displaced. There is less downward force than buoyancy (upward force).

This theory is invented by Archimedes . A great scientist. You should remember his name on your video.

christ guys stop hating on this guy he's making it simple for kids

[wilhelmthomsen]

1:18 he says when you put an ice cube in a cup. Notice the fancy equation. The 'ice cube' is not floating.
And he has been trying to explain buoyancy all video...

[MessiVsRonaldofan]

I wonder does density have a say in this. Kind of like how you said that ice floats in water I thought that was because the ice is less dense than the water?

while in a cargo ship:
Why don't big ships sink?
: Unless you pray for it XD

Never been on a cruise but it fascinates me on how they are designed
