LAW TONG &AIDEN 2013/9/23 AP PHYSICS B Mr. Moss THE LAB OF ATWOOD Procedure: The purpose of this experiment was to verify the predictions of Newton’s Law for an Atwood machine‚ a simple machine constructed by hanging two different masses and from a string passing over pulleys and observing their acceleration.. Newton’s Law predicts that the acceleration should be proportional to the difference between the masses and proportional to their sum‚ where = 9.8 m/s2 is the

Motion in a Viscous Medium Aim The aim of this experiment is to measure the terminal velocity of spherical beads falling under gravity in a liquid determine‚ and hence determine its viscosity using Stoke’s law. Introduction When a stationary solid object is complete or partially immersed in a fluid‚ it experiences an upthrust or buoyant force. According to Archimedes’ principle‚ this buoyant force B is given by where ρ is the density of the fluid‚ Vs is the immersed volume of the

CHAPTER 1 INTRODUCTION BACKGROUND OF THE STUDY Fish is abundant in the Philippines and is the cheapest source of protein‚ thanks to advances made in aquaculture or fish farming. Aquaculture is contributing significantly to food security‚ livelihood‚ and the economy. It involves raising seaweeds‚ milkfish‚ tilapia‚ shrimp‚ oysters and mussels in tanks or enclosures‚ ponds‚ pens‚ cages and open coastal waters. Fish Farming has been practiced over a hundred of years. It is a viable‚ sustainable

Vaster Than Empires and More Slow. If you look up Ursula K. Le Guin’s website‚ you’ll see she’s an older woman‚ perhaps in her sixties or seventies‚ she is really very pretty for her age! She’s also got some amazing talent in that brain of hers. Le Guin has written many famous science fiction novels and short stories‚ including children’s stories. Her work includes “The Ones Who Walk Away From Omelas” and “Vaster Than Empires and More Slow”. I’ve read Omelas‚ and I enjoyed it very much; I even

seek"[1]) is a force that makes a body follow a curved path: its direction is always orthogonal to the velocity of the body‚ toward the fixed point of the instantaneous center of curvature of the path. Centripetal force is generally the cause of circular motion. In simple terms‚ centripetal force is defined as a force which keeps a body moving with a uniform speed along a circular path and is directed along the radius towards the centre.[2][3] The mathematical description was derived in 1659 by Dutch physicist
