Archimedes' Principle of Ship

 ASSALAMUALAIKUM 

I'm Nur Anis Sofea want to make explanation about application of Archimedes' Principle for ship that have been taught by Puan Nurul Wahida to us.

The diagram below is the example of Archimedes Principle of Ship:



1. A ship though very heavy, floats in the sea. This is because the volume of sea water displaced by the ship is sufficiently large to have a weight equal to the weight of the ship.

2. Although a ship is constructed of metal, which has a greater density than water, its shape is hollow so that the overall density of the ship is less than the sea water. As a result, the buoyant force acting on the ship is large enough to support its weight.

3. The density of sea water varies with location. To ensure that a ship is loaded to within safety limits, the Plimsoll line marked on the body of the ship acts as guide.

4. A ship will submerge deeper in fresh water because the density of fresh water is less than sea water. This is why a ship must displace more water to obtain sufficient buoyant force to support its weight.

5. A ship can also float higher in cold seasons because of the higher density of cold water.

Based on my understanding, I understood 70% about this concept. Now I'm getting to more understand about the buoyant force of the ship. I will more focus and ask my teacher to get more information about this concept.

I'm Nurul Aqilah was understood about 75% when I learned Archimedes' Principle of ship. I will do more practice to enhance my understanding about this concept.

Archimedes' Experiment

The example of Archimedes Principle's experiment :


 

I'm Anis Sofea, based on my observation on the experiment, the way that he was handle the weight scale is wrong. The weight scale must be hanged to get the correct reading. But, in our own experiment, we have obtained the correct reading.

Me, Nurul Aqilah have observed this experiment, he must not use his hand to hold the weight scale. It were affect the reading of the weight scale when record the reading. In the other hand, our experiment was totally done with the correct reading of the weight scale.

 ~ ASSALAMUALAIKUM ~ 

Me, Nurul Aqilah represent my group would like to make an assessment of teaching and learning about Archimedes' Princle that have been taught to me by teachers Nurul Wahida. The definition of Archimedes' Principle is when an object is totally or partially immersed in a fluid, the upthrust or buoyant force on it is equal to the weight of fluid displaced. There are many types of application of Archimedes' Principle such as hot air balloon, cartesian diver, airship, submarine and many more :) 

The diagram below is the examples of Archimedes' Principle :
Based on my understanding, i just can understand about 65% when i learning about Archimedes Principle. Its a fun topic i guess but i think its not so easy. I was just lack of understanding about how to uses the formula. For sure, i will study hard for it. Thank you :)

Heyy, me Anis Sofea understood 75% when i've learned about Archimedes Principle. Im felt happy when i've learned about Archimedes Principle but its not as easy as i thought, maybe i need more practice so i will be more understand about it ♥
