Principles Density The density pronounced rho of an object is the ratio of its mass to its volume Since very few substances have exactly the same density this property can be used to identify an element or compound Buoyant Force When you are swim. Universal gravitational constant G667 x 10 11 Nm kg 2 2 EPS 122 Lecture 14 Gravity and isostasy Theory of gravity Gravitational potential Definition The gravitational potential V due to a point mass m at a distance r from m is the work done by th Archimedes Archimedes who combined a genius for mathem atics with a physical in sight must rank with Newton who lived nearly two thousand years late r as one of the founders of mathematical physics Alfred North Whitehead Archimedes was the finest sc Learning objective: . I can:. -describe and draw a diagram of the buoyant force on an object.. What is buoyancy?. Buoyancy is. There are 3 types of buoyancy. Archimedes. Who was he?. Archimedes Principle:. LESSON 2. Buoyant Forces and Liquid. Buoyant Force is an upward force which acts on an object that is being completely or partially immersed in a fluid. Example. Archimedes’ Principle. It states that for a body completely or partially immersed in a fluid, the upward buoyant force acting on the body is equal to the weight of the fluid it displaces.. 1 Buoyancy and Archimedes 287 BC - 212 BC. Archimedes of Syracuse was a Greek mathematician, physicist, engineer, inventor, and astronomer. Although few details of his life are known, he is regarded as one of the leading scientists in classical antiquity. Among his advances in physics are the foundations of hydrostatics, statics and an explanation of the principle of the lever. He is credited with designing innovative machines, including siege engines and the screw pump that bears his name. Modern experiments have tested claims that Archimedes designed machines capable of lifting attacking ships out of the water and setting ships on fire using an array of mirrors.. Physics. February 22/23. Will It Float?. Read section 19.4 and 19.5. Also, consider what we have already studied. See if you can list the reasons why an object will float. An object floats if:. Buoyant force larger than downward force of weight. Density – Is its mass per unit volume. . . 1. Formula = Density = mass/volume. . = g/mL or g/cm. 3. . *How tightly packed the atoms are. . 2. By comparing densities you can predict whether an object will float or sink in a fluid. An object that is more dense will sink, an object less dense will float.. Yewande Dayo. Student Pharmacist.
