BUOYANCY PHYSICS Student: Instructor: Criteria : Design Introduction The purpose of this experiment to find the effect of temperature on buoyancy . Backround Information Buoyancy (also known as the buoyant force) is the force exerted on an object that is wholly or partly immersed in a fluid. The symbol for the magnitude of buoyancy is B or FB As a vector it must be stated with both magnitude and direction. Buoyancy acts upward for the kind of situations encountered in everyday experience

Douglas Adams is indisputably hilarious. I don’t know how he did it‚ frankly‚ but even after having read this book at least once a year for over ten years‚ I still snicker at the funny bits every time. And The Hitchhiker’s Guide to the Galaxy is packed with funny bits. Adams has a talent for taking jokes and comedic elements just far enough - not too far‚ but not too staid and traditional either. His dry wit is evident in every line‚ and he knows exactly where to twist the plot back and pull all

Energy Energy can neither be created or destroyed‚ only changed into different forms. Energy is only useful when it can be converted into different forms. Energy is often dissipated - spread out and lost. 9 types of energy: Thermal (heat) - flows from hot to cold objects Kinetic (movement) - anything that is moving has this Light - from the sun‚ light bulbs et cetera Elastically potential - when things are stretched Gravitational potential - anything that can fall Electrical - whenever

Pendulum Raiyan Hassan SPH3U September 20‚ 2011 Introduction A pendulum is a device which consists of a mass attached to a string from a frictionless pivot which allows it to swing back and forth. In this experiment‚ the time it takes for a pendulum to go through a period is going to be measured. The time it takes for a pendulum to go through one period can depend on factors such as the length of the string‚ mass‚ or the degree in which the pendulum is released from (amplitude). In this

Book Review: The Hitchhiker’s Guide to Lean: Lessons from the Road “Hitchhikers don’t travel a fixed path. They intentionally wander so they can learn and change along the way. Embarking on the lean journey is similar‚ there are many roads on which to wander and no single one is right for all.” These words serve as a very intriguing introduction to the book‚ The Hitchhiker ’s Guide to Lean: Lessons from the Road‚ co-authored by Jamie Flinchbaugh and Andy Carlino and published by the Society of

Chapter 13 – States of Matter Pressure (P) – the amount of force per unit area. Pressure=F/a or P=F/a Pascal’s Principle “Any change in pressure at a point on a confined fluid is transmitted throughout the fluid”. Any change is transmitted throughout the fluid. Buoyancy & Archimedes Principle “When an object is submerged in a fluid‚ it displaces a certain volume of that fluid. The amount of force pushing upward on the object is equal to the density of the fluid (Ï) times the acceleration
