The document presents an overview of Archimedes' principle, which explains that an object immersed in a fluid experiences an upthrust equal to the weight of the displaced fluid, governing behaviors such as floating and sinking. It discusses applications of this principle, including the behavior of hot air balloons, and touches on material considerations in ship construction. Additionally, it includes references to various academic sources and interesting facts about buoyancy in the Dead Sea.

4. The law
 Archimedes' Principle, law of
physics that states that when an
object is totally or partially
immersed in a fluid, it
experiences an upthrust equal to
the weight of the fluid displaced.
The principle is most frequently
applied to the behaviour of objects
in water, and helps to explain
floating and sinking, and why
objects seem lighter in water. It also
applies to balloons in the air.

5. Buoyant Force and Floatation
Buoyant force = weight ⇒ the object floats and stationary
Buoyant force > weight ⇒ the object moves up
Buoyant force < weight ⇒ the object moves down

THINK!!!!!
1. Why the depth of ship immersed in the water different?

7. Fresh water less dense than sea water and warm
water less dense than coldwater so warm fresh
water need to be displaced more to keep the
uptrust force equal with weight of the boat so it
still can float.

8. APPLICATIONS
Hot air balloon
1. rises upwards
(Upthrust > Weight of hot air (helium gas) +
weight of airship fabric + weight of gondola +
weight of passengers.)( balloon expand)
2..descends
(Upthrust < Weight of hot air (helium gas) +
weight of airship fabric + weight of gondola +
weight of passengers.)(balloon shrinks)
3. stationary
(Upthrust = Weight of hot air (helium gas) +
weight of airship fabric + weight of gondola +
weight of passengers.)( balloon size uncanged)

13. DO YOU KNOW??
TheDead sea’susually high salt concentration meansthat peoplecan easily float in thedead seadueto
natural buoyancy. In thisrespect theDead issimilar to theGreat Slat Lakein Utah in theUnited states.
TheDead Seaisroughly 8.6 timessaltier than theOcean.
