Archimedes PrincipleHukum Archimedes

Archimedes Principle , which states that “ when a objects is immersed in a fluid ,the apparent loss of weight of an objects is equals to the upthrust and this is also equal to the weight of the displace fluid “. Hukum Archimedes menyatakan bahwa “ bila sebuah benda dimasukan dalam zat cair, besar gaya apung benda sama dengan gaya angkat yang besarnya sama dengan berat benda yang dipindahkan ke zat cair “. Archimedes principle is mathemathically formulated as ( secara matematis , hukum archimedes dirumuskan ) :

Where FA is bouyant force , ρf is densiti of fluid , and Vbf is the volume of immersed body. Dimana FA adalah gaya apung , ρf adalah massa jenis fluida , and Vbf

adalah volume benda yang tercelup.There are three possible case of a body in a fluid , i.e floating, barely floating

and sinking. Ada tiga keadaan benda dalam zat cair, yaitu terapung, melayang dan tenggelam.

1. Floating Terapung

A object is said to be floating if only some of parts of the objects is beneath the water surface and the other parts is above the water surface.Benda dikatakn terapung jika sebagian dari benda berada dibawah permukaan air dan bagian yang lain berada diatas permukaan air. The magnitude of bouyant force is equals to the body’s w.Besarnya gaya Archimedes sama dengan berat benda.

FA = mgVf ρf g = Vb ρb g

Vf ρf = Vb ρb

FA = ρf Vbf g

2. Barely FloatingMelayang

On barely floating objects , the magnitude of bouyant force is equal to the objects weight.Pada benda melayang besarnya gaya Archimedes sama dengan berat benda.Hence for a barely floating objects we have the relation Syarat benda dikatakan melayang adalah ρf = ρb .

FA = wVf ρf g = Vb ρb g

ρf = ρb

3. Sinking Tenggelam

When an object is sinking its means that the bouyant force acts on the object is smaller than its weight. Pada saat benda tenggelam besar gaya Archimedes lebih kecil dari berat benda. The volume of the immersed objects equals to the total volume of the objects. Volume benda yang tercelup sama dengan volume benda. An Object sinks in a fluid when density is greather than the density of the fluid.benda akan tenggelam dalam zat cair jika massa jenis benda lebih besar dari massa jenis fluida.

FA > wVb ρb g > Vf ρf g

ρb > ρf

Archimedes Principle is widely used in either technology or science. Prinsip archimedes banyak diterapkan baik dalam tekologi atau sains. Some example of device that work based on it (beberapa contoh alat yang menggunakan prinsip itu :

Ask This activity is entirely performed by the students reflects the seriousness and high learning interest and dare convey and embody in the points question. Students have the opportunity to ask questions directly and varied to teachers according to what is observed Teachers assess learners' skills to question Try Learners are divided into small groups, each consisting of 4 people Learners in the group was asked to conduct experiments Archimedes law in accordance with the steps on Worksheet (Appendix 1 Meeting 3) Learners observe the experiment. Representatives of the group recorded the results of the experiment Teachers assess the attitudes of students in group work and guided / assess skills try, use tools, and process data, as well as assessing the ability of students apply the concepts and principles in problem solving Teachers assess the attitude of the learners in the group work associate Each group discussed the results of the experiment, then concludes results of experimental laws of Archimedes Teachers guide / assess the ability of learners to process the data and formulate conclusion Communicating Representatives of the two groups present their The group discusses troubleshooting Teachers assess the ability of learners to communicate verbally
