Archimedes Principle.

Below is the the diagram of a ship.

Seriously,I'm not talented in drawing.

1. The physical principle that explains the situation above is Archimedes principle.
2. The ship is floating partially in the sea water because the weight of the ship is equal to the upthrust(buoyant force) and the resultant force is zero.

• A point to remember:

A ship is made by steel do not sink because,

1. Contains air space to displace the sea water.
2. Upthrust is great enough to support the weight of ship.
3. Steel ship is hollow inside hence,density of ship < sea water.

In conclusion:

-Shahirah,Nurin,Fatimah and Iffah understood the Archimedes principle taught by our teacher.
