Archimedes' principle
Archimedes was born in 287 BC in Syracuse, Greece. He died in 212 BC when he was killed by a Roman soldier who did not know his identity. Archimedes' father was named Phidias and may have been related to Hieron II, the king of Syracuse. Archimedes' Principle states that when a body is immersed partially or fully in a fluid, it experiences an upward force equal to the weight of the fluid displaced by the body. This upward force is called the buoyant force. The buoyant force depends on the volume of the body immersed and the density of the fluid. An experiment is described to verify Archimedes' Principle by measuring the loss in weight of a

This document discusses Archimedes' principle of buoyancy. It explains that Archimedes' principle states that when an object is submerged in a fluid, it experiences an upward force equal to the weight of the fluid displaced. This upward force is called upthrust or buoyant force. The principle explains why objects float or sink based on an object's density compared to the fluid density. Applications of the principle include ships, submarines, hot air balloons, and hydrometers.
Archimedes principle
The document discusses buoyancy and how objects float or sink in water. It states that an object's apparent weight is less than its actual weight when submerged due to buoyant force. Buoyant force equals the weight of fluid displaced and is equal to the actual weight minus the apparent weight. A boat made of steel floats because its large size and hollow shape displace a large volume of water, creating enough buoyant force to support the boat's weight, while a solid steel block sinks because it only displaces a small volume of water, resulting in insufficient buoyant force.
Archimedes principle
Archimedes' principle states that the buoyant force on an object submerged or partially submerged in a fluid is equal to the weight of the fluid the object displaces. This principle can be used to calculate density and relative density. It also explains why ships and submarines float or sink depending on whether the object's density is greater than, equal to, or less than the fluid it is placed in. Applications of Archimedes' principle include ship building, submarine operations, and how certain aquatic animals and balloons are able to achieve buoyancy.

power point presentation on Pascals law and its applications for ICSE class IX
Pascal's Law states that pressure applied to any part of a confined fluid is transmitted equally in all directions and acts at right angles to the surface of the containing vessel. The document discusses Pascal's Law and its applications, with one example being the hydraulic press, which uses Pascal's Law to multiply force by transmitting fluid pressure through confined liquid.
Pressure
Pressure is defined as force per unit area. Several examples are given to illustrate that pressure increases when a force is applied over a smaller area. Pressure also increases with depth in liquids and density of the liquid. Various instruments are discussed for measuring pressure, including manometers, mercury barometers, aneroid barometers, and pressure gauges. Pascal's principle of transmission of pressure in liquids is demonstrated through experiments. Applications of pressure in hydraulic machines, bicycle pumps, lift pumps, force pumps, and siphons are also described.
Density Ppt
Density is a measurement of how tightly matter is packed together in an object. It is calculated by dividing an object's mass by its volume. Ice floats in water because it has a lower density than water - ice has a density of about 0.9 g/cm3 while water has a density of 1 g/cm3. Hot air balloons and magma rise because they have lower densities than the surrounding air and rock, respectively. A ship will float if its overall density is less than that of water, which is 1 g/cm3.

3) The document uses examples to demonstrate how to calculate buoyant force and determine if an object will float or sink based on its density compared to the fluid.
Thrust and pressure ppt
This document defines thrust as a force applied perpendicular to a surface, measured in Newtons. It explains that pressure is the effect of thrust per unit area, calculated as thrust divided by area, with units of Pascals. It provides examples of how pressure depends on both the applied force and the contact area, with greater force or smaller area resulting in higher pressure. Specifically, it notes that a sharp knife cuts better than a blunt one because the same force is applied over a smaller area, creating greater pressure.

Pressure in liquid
Pressure in liquid acts equally in all directions and is not affected by the shape, size, or surface area of the container. Pressure depends only on depth, with deeper depths experiencing higher pressure. Applications where pressure differences in liquids are used include water supply systems, which place reservoirs at higher elevations to provide water pressure to lower areas, and medicine infusion, where bottles are elevated to provide pressure to flow medicine into veins.
The kinetic theory of gases
The document discusses gases and their properties according to the kinetic molecular theory. It defines the key concepts of gases including their state, composition of molecules, and random motion. It also outlines the assumptions of the kinetic molecular theory for ideal gases and describes the variables used in gas laws - temperature, pressure, volume, and moles. Real gases are known to deviate from ideal behavior at high pressures or low temperatures due to intermolecular forces and molecular size.
Pressure in solids
This document defines pressure as force per unit area, with pressure measured in pascals (Pa) and force in newtons (N). It provides the formula for calculating pressure as pressure = force/area. It explains that cutting tools increase pressure by reducing the contact area, while caterpillar tracks reduce pressure from heavy vehicles by increasing their surface area and distributing the force over a larger area.
Relative Density Lesson Plan
This document outlines a lesson plan on density and relative density for 5th grade students. The lesson objectives are for students to compare which objects sink or float in water and to predict and test the relative densities of liquids including salt water. Students will conduct experiments placing various objects in water and salt water to observe if they float or sink. They will make predictions and analyze the results to determine if the objects are more or less dense than water. Modifications for English language learners and special education students are provided, such as extended time, picture vocabulary, and lab assistants.
solution and solubility
A solution is a homogeneous mixture composed of two or more substances. In a solution, the substance present in lesser amount is called the solute, which is dissolved in the substance present in larger amount known as the solvent. Common examples of solutions include sugar dissolved in water and gases dissolved in liquids. The concentration of a solute in a solution depends on how much of the solute is dissolved in the solvent. Solutions are homogeneous mixtures where the solute and solvent are mixed uniformly throughout the solution.
Pressure in fluids
Liquids and gases exert pressure equally in all directions. Pressure increases with depth in liquids and gases due to the weight of the fluid above pressing down. Magdeburg hemispheres demonstrate that air pressure keeps spheres stuck together when the air between them is removed. The formula for calculating fluid pressure is Pressure = Density x Gravity x Height, where increasing height results in increasing pressure.
Conservation Of Momentum
The document discusses collisions and the law of conservation of momentum. It provides examples of how to use a momentum table and algebra to solve for unknown velocities in collision problems involving isolated systems where momentum is conserved. Specifically, it works through examples of a person catching a medicine ball on ice and of two people colliding on an ice rink to determine their combined velocity after collision.
Archimedes principle
Archimedes' Principle states that the buoyant force on an object immersed in a fluid is equal to the weight of the fluid displaced by the object. This principle explains why objects float or sink based on an object's density compared to the fluid. It also explains why objects seem lighter when submerged. Applications of Archimedes' Principle include determining the depth ships sit in water based on water temperature and density, how hot air balloons rise and fall, and how submarines control their buoyancy using ballast tanks.
Buoyancy & floatation
1) Buoyancy is the upward force exerted by a fluid that opposes the weight of an immersed object. This force is equal to the weight of the fluid displaced by the object and allows objects with lower density than the fluid to float.
2) The key factors that determine if an object will float or sink are the density of the object compared to the fluid density, the weight of fluid displaced versus the object's weight, and the object's shape.
3) Stability of floating objects depends on the location of the meta-center point, which is where the line of buoyancy force meets the axis when tilted. Stable equilibrium requires the meta-center to be above the center of gravity

Objects float if they are less dense than the fluid they are in, while objects sink if they are more dense. Density depends on an object's mass and volume. Ships and submarines are able to control whether they float or sink by changing their overall density, either by changing their mass through adjusting ballast, or changing their volume. Archimedes' principle explains that the buoyant force on an object equals the weight of the fluid it displaces.
Density 3
This document provides notes on the law of floatation in physics. It begins with an introduction to the blog and defines floatation as the tendency of an object to rise or stay at the surface of a fluid.

Some of his key contributions include developing mathematical principles for calculating the surfaces and volumes of spheres and cylinders, accurately approximating pi, and inventing early machines and tools still used today such as the Archimedes screw for irrigation. He made groundbreaking discoveries in mathematics and physics, including formulating the law of buoyancy known as Archimedes' principle.
Floating and sinking
The document discusses floating and sinking concepts including:
1) Objects float if they are less dense than the fluid they are in and sink if more dense. Density is mass divided by volume.
2) Archimedes' principle states the buoyant force on an object equals the weight of the fluid it displaces.
3) Objects can change their density and therefore floating/sinking by changing their mass like submarines, or volume like ships.
ROLE OF DENSITY IN SHIPS AND AIRCRAFT INDUSTRIES
The document discusses the importance of density in the ship and aircraft industries. It defines density and explains that an object's density determines if it will float or sink in water based on Archimedes' principle. Ships are able to float because they displace a volume of water with a mass less than the mass of the displaced water, creating an upward buoyant force. Aircraft carriers in particular float due to their large size distributing their weight across a wide area, balancing water pressure. In aviation, air density affects lift and engine performance, as lower density means lower aircraft performance.
Forces in Fluids
The document summarizes key concepts about fluids and their properties. It explains that fluids exert pressure evenly, and pressure increases with depth. It also discusses how atmospheric pressure varies with altitude. Objects float based on buoyant force balancing their weight. Denser objects sink while less dense objects float. Fluids flow from high to low pressure. The document also examines how fluid speed relates to pressure through Bernoulli's principle and how wing design and size influence flight.
fluids # 1.pptx
- Water pressure increases with depth due to the weight of the water above pushing down (P1). This is why fish eyes pop out - their bodies are not adapted to sudden changes in pressure (P2).
- Air pressure decreases with increased elevation since there is less air above pressing down. This is why ears pop on planes or mountains as the pressure outside the body changes faster than inside (P3).
Topic: Buoyancy – Naval Architecture Group 2
Buoyancy is the upward force exerted by a fluid on an object submerged or partially submerged in it. The buoyant force depends on the volume of fluid displaced by the object and the density of the fluid. Objects with densities lower than the fluid they displace will float due to positive buoyancy, while objects with higher densities will sink due to negative buoyancy. The location of an object's center of buoyancy relative to its center of gravity determines its stability in a fluid.

The paper goes on to describe the water cycle, composition and coverage of oceans, ocean currents driven by both winds and water density, ocean waves, and ocean floor topography including trenches, ridges, and seafloor spreading. Overall, the document analyzes the hydrosphere through a religious lens, seeing layers and interconnected processes as metaphoric of the holy trinity and God
Fluid Properties ppt.ppt
This document discusses key principles relating to fluids and their properties:
- Archimedes' Principle explains how buoyancy allows objects to float if the fluid displaced weighs more than the object.
- Density measures the mass per unit volume of a substance.
- Pascal's Principle describes how pressure is transmitted equally in all directions throughout a fluid.
- Bernoulli's Principle relates the pressure of a fluid to its velocity. As velocity increases, pressure decreases.
- Boyle's Law states that as a gas is compressed into a smaller space, its pressure increases.

This document provides an overview of wound healing, its functions, stages, mechanisms, factors affecting it, and complications.
A wound is a break in the integrity of the skin or tissues, which may be associated with disruption of the structure and function.
Healing is the body’s response to injury in an attempt to restore normal structure and functions.
Healing can occur in two ways: Regeneration and Repair
There are 4 phases of wound healing: hemostasis, inflammation, proliferation, and remodeling. This document also describes the mechanism of wound healing. Factors that affect healing include infection, uncontrolled diabetes, poor nutrition, age, anemia, the presence of foreign bodies, etc.
Complications of wound healing like infection, hyperpigmentation of scar, contractures, and keloid formation.

Archimedes Principle
- 2. BAHRIA UNIVERSITY LAHORE CAMPUS (CIVIC CENTER JOHAR TOWN LAHORE) NAME: FARAZ QURESHI SAFI ULLAH SHAHID CLASS: BS(CS)1 SUBJECT: PHYSICS INCHARGE: SIR ZAIN
- 4. Archimedes was one of the greatest mathematicians in history. He was also a great inventor and scientist. Born in Syracuse, Sicily (then part of Greece), in about 287 B.C. Archimedes was obsessed with mathematics. He would become so involved in his work that he would forget to eat. Out of this obsession came many of his greatest theories and proofs, such as the means for approximating square roots, the value of pi (the ratio of a circle's circumference to its diameter), and the creation of a way to describe very large numbers. He also devised methods for calculating areas and volumes 2,000 years before the invention of calculus. In addition, Archimedes proved that the volume of a sphere is two-thirds the volume of a circumscribed cylinder. Archimedes was well known for his inventions and scientific discoveries. The most famous of these were the Archimedes' Screw (a device for raising water that is still used in crop irrigation and sewage treatment plants today) and Archimedes' principle of buoyancy. Legend has it that he discovered this principle while in the bath, where he noticed that the more of his body he submerged in the water, the greater the amount of water that over-flowed the bath. Upon making this discovery, he is said to have run naked through the streets of Syracuse, shouting "Eureka!" (Greek for "I have found it!").
- 5. Archimedes Principle states that when a body is partially or completely immersed in a fluid, it experiences an apparent loss in weight due to up thrust force and this apparent loss in weight is equal to the weight of the fluid displaced by the immersed part of the body
- 6. is an upward force resulting from an object being wholly or partially immersed in a fluid.
- 8. The weight of an object in air is its actual weight . The weight measured when the object is immersed in a fluid is its apparent weight. The apparent weight loss of the object is due to buoyant force.
- 9. The actual weight which acts downwards . The buoyant force which acts upwards.
- 13. Although a ship is constructed of metal, which has a Larger density than water, its shape is hollow so that the overall density of the ship is smaller than the sea water. As a result, the buoyant force acting on the ship is large enough to support its weight.
- 14. A submarine has a large blast Tank, which is used to control its position and depth from the surface of the sea. When a blast tanks are filled with water, its buoyant force is smaller then the weight of submarine. So the submarine is sink When a blast tanks are filled with air, its buoyant force is larger then the weight of submarine. So the submarine is float.
- 15. When the envelope of a balloon is filed with a gas of lower density that air such as Hydrogen, Helium or hot air, its weight decreases. Hot air has a lower density than surrounding air resulting in a bigger up thrust that cause the balloon to rise. Its means the buoyant force is larger than the total weight of the balloon.
- 16. Air ships is filled with helium Gas. Helium gas has density lower than the surrounding air, hence the up thrust which higher than the weight of the airship can be produced and cause the air ship float the air.
- 17. Hydrometer is used to measure relative density of liquids. How deep the hydrometer sink into the liquid is affect by the density.
