Question 13
H

A cargo ship floats in the sea.

Explain, using ideas about pressure in a liquid, why there is an upward force on the ship.

Use these ideas to explain why:

  • the ship floats even though it is made of steel
  • the ship floats lower in the water when it is loaded with cargo
  • the ship floats lower in fresh water than in sea water.
