This is a video of a truck getting thrown off of an aircraft carrier. When it hits the water, it bounces off instead of sinking. Why?

look up physics of stone skipping

B-but that's why I came here.
>>8044974
Surface tension of water, a big chunk of the kinetic energy in the truck is reflected back when it hits
>>8044969
of far more importance is WHY the truck was flown off the aircraft carrier. remember, without philosophy, science is a blind man stumbling in the dark.

The object compresses the water as it hits it and the water pushes it up again as it decompresses, a bit like a trampoline. If the angle is right and the object has enough forwards momentum to continue despite the friction of the water, then the object will be ejected and can potentially do another skip.
As you can see in your webm, it works best if the object is hitting the water with a big flat surface. The perfect entry angle appears to be 20 degree. If the object gets ejected and enters the water at a similar degree angle again, then it will do another skip if it still has forwards momentum.

This is the worst camera man on earth.

Very nice. The vehicle is lighter than the water according to its speed as it headed toward the water so it bounces off.

At least give us one inside the truck.
Think of water as a trampoline. It will bounce off it cause water tension

>surface tension
More like density and dynamic pressure.
