Damped Harmonic Motion Erica Partner: Steven November 8‚ 2012 Abstract During this experiment‚ the effects that the size of an object had on air resistance were observed and determined. To do this‚ a spring was set up with a circular object hanging at the end. After the spring constant of 9.0312 N/m was measured‚ equations were used to determine a calculated frequency‚ that being 7.252 Hz. Four trials—each with a different sized‚ same massed object—took place where the object was pulled

Introduction- The purpose of this experiment is to obtain isolation of individual species of particles from the mixed culture. This is completed through the isolation technique of streak plate. The objective of this experiment is to replicate the technique of streak plate but on a much larger scale. Because it is on a larger scale the particles are able to be visually observed as they are isolated using the streaking technique as the experiment is conducted. The benefits of the streaking technique

Name(s)_____________________ HOOKE’S LAW and SIMPLE HARMONIC MOTION INTRODUCTION Any motion that repeats itself in equal intervals of time is called periodic motion. A special form of periodic motion is called Simple Harmonic Motion (SHM). Simple Harmonic Motion is defined as oscillatory motion in which the resultant force on the oscillating body at any instant is directly proportional to its displacement from the rest position and opposite in direction to its motion. For a spring system‚ this can be written

How Sugar Affects the Body in Motion By GRETCHEN REYNOLDS Gary John Norman/Getty Images Sugar is getting a bad reputation. A cover article in The New York Times Magazine several weeks ago persuasively reported that our national overindulgence in fructose and other sugars is driving the epidemics of obesity‚ diabetes and other illnesses. But that much-discussed article‚ by the writer Gary Taubes‚ focused on how sugars like fructose affect the body in general. It had little opportunity to examine

“THE EFFECT OF AIR RESISTANCE WITH RELATIONSHIP TO THE AREA OF THE PAPER IN FREE FALL MOTION” An Investigatory Project I-INTRODUCTION A. Background of the Study When an object is dropped‚ the force of gravity will cause it to speed up as it falls. But friction with the air‚ called drag‚ will tend to cause it to slow down. How much drag there is depends mostly on two factors: speed and shape. The faster an object moves through
