1Experiment 11 Prepare for this weeks quiz by reading the seat cover Archimedes pronounced rho of an object is the ratio of its mass to its volume Since very few substances have exactly t. 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 Principle. Physics. February 17/21. Pressure Review. What affects the pressure of a liquid?. The Density of the liquid . The depth of the liquid. The speed the liquid molecules. What affect the pressure of the air (atmospheric pressure)?. 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.. Buoyancy . a. nd. Archimede’s. Principle. Buoyancy and Buoyant Forces. When you are swimming in. water, there are two forces that. work against each other and. affect the motion of your body. . the force of gravity is pulling you down . Contents:. How to calculate. Whiteboards. Buoyant force is the weight of displaced water:. ρ. f. = Density of fluid in kg m. -3. V. f. = Volume of displace fluid in m. 3. g . = . 9.81 N kg. -1. Buoyant Force. Buoyant force is the upward force that fluids exert on all matter. . A great example is how a rubber duck floats in a bath tub. . Buoyant Force is Caused by Differences in Fluid Pressure. A Brief Timeline of the . Discovery of Gravity. Aristotle. There . is . no effect or motion without a cause. . . The element of earth was thought to be heavy by nature and therefore pulled towards the centre of the (geocentric) universe.. 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. Danielle DelVillano, Pharm.D.. Objectives. Define density, specific gravity, and specific volume and determine each through appropriate calculations. Apply specific gravity correctly in converting weight to volume and volume to weight. Unit 2. Forces. A . force. is a push or pull. .. When forces are . balanced. matter is . still. .. When forces are . not. balanced matter will . move. .. Gravity. Gravity is a . force. that . pulls. Stations 1-10. 1. What forces are involved in making a hot air balloon move?. 1. Up and Down Forces. Lift pushes the balloon up . against . the downward force of . gravity. .. Lift is due to the density inside . Convert the following to scientific notation. Distance from Sun. : 92,960,000 . miles ____. Estimated Age of universe – 14,000,000,000. Convert the following to standard form. Speed of light = 9.0 * 10. Forces & Gravity. Notes. Write down the words in yellow.. The words in white are discussion points, you may write these down, but are not required.. Gravity. Gravity is a . force. that pulls objects toward each other..
