  3.5….ARCHIMEDES’ PRINCIPLE
• 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.

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

  warm fresh water cold fresh water warmsea water cold sea water THINK!!!!! 1. Why the depth of ship immersed in the water different?
• 7.
  Fresh water lessdense 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.

  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)

  DO YOU KNOW?? TheDeadsea’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. INTESTING FACTS…!!! FLOATING IN DEAD SEA WATER
