...Phvsics Lab Report Format (Sample Report Attached) General Remarks: Writing a lab report is the only way your TA will know what you have done during the lab and how well you have understood the process and the results. Part of your lab experience should be learning how to organize and present your work in a scientific way. There is no framework that can be used as a "one size fits all", therefore this sample lab report should only be used as an example. Any lab report should have the following features: o It should be concise but should also contain the necessary details and well-developed explanations. It should be organized. You should enable the reader to quickly find the information he or she may be interested in. It should contain all the relevant information and reasoning. You should enable the reader to validate your conclusion. A possible way to achieve this is using the following framework: o o . o o o o . Obiective: State what you want to achieve in this experiment A formal way to do this is to state a question or hypothesis that you want to address. Method: You should include a summary of the lab procedure in your words; do not merely copy what is in the manual. This section should demonstrate your understanding of what exactly you measured and how you measured it. Data: In this section you should include the raw data you measured; generally, an estimate of the error should accompany all measured values. Be sure to present...

When your lab report is complete, submit it to the Submitted Assignments area of the Virtual Classroom. Part I – Answer the following questions while in the Phase 5 lab environment. Section 1 – From the left of the screen to the right, the red balls have a center of mass placed at 20 feet, 15 feet, and 10 feet high respectively. 1. Suppose each red ball weighs 20 lbs. Find the potential energy (PE) for each ball on each ramp. In this lab mass is given in pounds and height is in feet, so use 32.2 ft/sec2 as the gravitational constant. Your answer will be in foot-pounds since US units are being used. PE = m g h where g = 32.2 ft/sec2 Ramp 1: Potential energy is 541.21 Ramp 2: Potential energy is 406.21 Ramp 3: Potential energy is 271.10 2. Predict the maximum speed (velocity) of each ball on each ramp. How would this speed change if each ball’s mass was doubled? ASSUMPTION: assume there is no friction and that all the potential energy you calculated in question 1 is transformed into kinetic energy – PE = KE. Use the following equation. KE= ½ m v2 You want to calcu-late v maximum speed v = [KE/ ½ m]½ This means divide the KE by half the mass and then take the square root.

...NUTRITION 121 HUMAN NUTRITION LABORATORY BACKGROUND AND METHODS MODULE #1 BODY COMPOSITION Late Labs: 10 point deduction! A report submitted >1 week late, will receive 0 points for the lab!! Written and edited by: Karon Felten and Nutrition 121 TA’s With Special Thanks to: Chris Pritsos Ph.D. Nutrition Department Chairman ABSTRACT: In nutrition, there are many factors that influence an individual’s health and body weight, such as heredity, food selection, eating behaviors, and physical activity. Scale weight is not always a good indicator of body fat, lean mass, body water or overall health (1). This laboratory experience will give students the opportunity to conduct physical assessments by evaluating body weight and body composition. To determine body weight and body composition, techniques such as bioelectrical impedance analysis (BIA), body mass index (BMI), waist circumference, wrist circumference for determining frame size, and a scale will be utilized. Students will also evaluate their own risk for cardiovascular disease and assess cardiovascular health in volunteers by measuring heart rate, filling out a heart disease risk score form, and estimating oxygen consumption and energy expenditure through a technique known as the Queens College Three-Minute Step Test. BACKGROUND: Your body is made up of the six essential nutrients: water, fat, protein, carbohydrates and various vitamins and minerals. Many factors can influence an individual’s...

...Lab Assignment 4: Types of Force Instructor’s Overview In many physics problems involving Newton’s laws of motion, you’ll see statements like, “assume a frictionless surface” or “neglecting air resistance…” In this lab we will be exploring both friction and air resistance, two resistive forces that are critical in the design of real-world products and systems. Understanding the effects of these types of forces is essential in the design of such things as aircraft, automobiles, braking systems, and countless other objects. This activity is based on Lab 4 of the eScience Lab kit. Although you should read all of the content in Lab 4, we will be performing a targeted subset of the eScience experiments. Our lab consists of two main components. These components are described in detail in the eScience manual. Here is a quick overview: * In the first part of the lab, you will measure the force it takes to pull objects of different mass. This experiment focuses on the effects of frictional forces. (eScience Experiment 1) * In the second part of the lab, you will investigate the effects of air resistance by performing controlled drops of coffee filters. Notes: * Please follow the instructions in this document for the air resistance experiment. * Record all of your data in the tables that are provided in this document. Take detailed notes as you perform the experiment and fill out the sections below. This document serves as your lab report. Please...

...Lab Report- Calculate and Prove the Acceleration Due to Gravity David Chen Introduction: We know that the acceleration due to gravity on the earth is 9.8ms -2. This acceleration is very important since we can use it to calculate gravity force, mass, and so on. In this lab, we use a free fall object to calculate its acceleration due to gravity to check if it is 9.8ms-2. We use the acceleration formula a=V2-V1t2-t1 to calculate the acceleration. Hypothesis: The acceleration due to gravity on the earth is 9.8ms -2. So in this lab, the acceleration in the result should also be 9.8ms-2 since the object experiences the free fall on the earth. Diagram: Free fall object diagram Free fall object diagram Motion detector Motion detector 1 meter 1 meter Point 2(V2 T2) Point 2(V2 T2) Point 1(V1 T1) Point 1(V1 T1) Free fall object Free fall object Method: In this lab, we used a motion detector to measure the velocities and times of the falling object. The range of the motion detector is one meter, so we have to drop the object from one meter above the ground. So to make the result more accurate, first we placed the motion detector on the top of the metal ring which is approximately one meter above the ground. After that we held the object under the motion detector. Then we started the motion detector and dropped the object at the same time. At last we observed the data in the computer provided by the motion detector. We chose two points which the falling object...

...9-705-448 REV: NOVEMBER 2, 2005 GIOVANNI GAVETTI REBECCA HENDERSON SIMONA GIORGI Kodak and the Digital Revolution (A) In February 2003, Daniel A. Carp, Kodak’s CEO and chairman, reviewed 2002 sales data with Kodak’s senior executives. Film sales had dropped 5% from 2001 and revenues were down 3%. 2003 did not look any brighter: Carp expected revenues to grow only slightly and net income to remain flat or decrease (see exhibit 1 for information on Kodak’s financial performance and exhibits 2 and 3 for information on sales of cameras and film rolls in the United States). The film industry was “under pressure unlike ever before.” Carp predicted a “fairly long downturn”1 for traditional photography sales as consumers turned to digital cameras, which did not require film. Kodak was moving more of its manufacturing to China, where it could boost film sales, and was planning to slash 2,200 jobs, or 3% of its work force, especially in the photo-finishing business. Carp had received a master’s in business from MIT. He had begun his career at Kodak in 1970 as a statistical analyst. Since then, he had held a variety of positions at Kodak. In 1997, he became president and COO, and was appointed CEO on January 1, 2000. He believed Kodak’s current struggle was one of the toughest it had faced. How could he use digital imaging to revitalize Kodak? Kodak, 1880-1983: A brief history In 1880, George Eastman invented and patented a dry-plate formula and a machine for preparing large...

Liquid is at 328K and appears to be closely bonded but moving around much faster. Gas is at 809K and appears to be moving much faster and occupying more space than solid and liquid. But when the temperature is reduced to about 97K the rate of movement decreases and the molecules get more clustered and compact, the reaction in liquid is almost the same as gas when the temperature is reduced to the same 97K. The reaction in solid liquid and gas stages of water are almost constant at a reduced temperature of 97K. Only the solid state resembles itself in heated and cooled stages. The others have different resemblance. In...

...CHEM 321 Experiment 1 Basics Review and Calibration of Volumetric Glassware There are three types of containers used in lab to contain or deliver liquids: volumetric, ordinary, and disposable glassware. Volumetric glassware are containers that have been calibrated at a specific temperature to deliver or contain VERY PRECISE amounts of liquid. Examples of volumetric glassware that we will use include burets, pipets, and volumetric flasks. Ordinary glassware has less precise volume calibrations and are used whenever the volumes do not have to be measured as accurately. Examples include beakers, Erlenmeyer flasks, and graduated cylinders. Disposable glassware (or plastic ware) is used to transfer or hold liquids temporarily and may not contain any volume markings. Examples include medicine droppers and disposable pipets. In this experiment you will be exposed to a variety of important concepts related to quantitative experimentation, including the proper use of glassware, analytical balances, and statistics. You will calibrate a volumetric pipet or flask, that is, you will experimentally determine what volume a pipet or flask really delivers. You will also calibrate a beaker or Erlenmeyer flask and a 50 mL buret. You will use these calibrated values throughout the remainder of the quarter. Construct a table at the front of your laboratory notebook to record calibration values or tape in the calibration tables from Chapter 2 of Harris’ 7th edition. How to read the level of liquid...

...first lab involved measuring g or measuring acceleration due to gravity. To measure the values of g we used two steel balls of different sizes, and dropped both balls from different heights. First we started by measuring the masses of each ball with the small steel ball having a mass of 15.8 grams, while the larger one had a mass of 28.8 grams a 13 gram difference. Then we dropped each ball from the same height starting at 87 centimeters. This measurement was from the bottom side of the ball to the timer pad. After both balls had been dropped at least three times from the same height, we would then change the distance that the balls fell. The height ranged from 87 centimeters down to 33.4 centimeters. The team measured the time that it took for each ball to drop from the starting point to the ground. We took a time measurement three times to be sure we some consistency. The following equipment was used to perform the experiment: * One 15.8 g steel ball * One 28.8 g steel ball * Timer (ME 9215A-1) * Triple Balance Beam (PHY 28) * Free Fall Apparatus (ME-9207B), Measuring Tape (39395).

...Lab Report 2 – Titration CHEM1903 – Chemistry 1A (SSP) Michael West (305159240) 1. Experiment 2.2 – Titrimetric determination of the molecular mass of an organic acid Method An unknown organic acid was supplied in solid form. The acid was known to be diprotic and had the reference number 19. Using an analytical balance, 1.5397 g of the acid were weighed out, and made up with deionised water into 250 mL of solution. 25 mL of the acid solution was added to a conical flask with phenolphthalein indicator and titrated against standardized 0.0983 M NaOH solution. Three titrations were performed and the results averaged. The molar mass of the acid was then calculated and compared to a list of given possibilities. Results and Calculations The three titres were 26.30 mL, 26.50 mL and 26.30 mL. The mean titre volume was hence 26.37 mL. The number of moles of NaOH was thus moles. Because the acid was diprotic, reaction stoichiometry dictates that there was one mole of acid for every two moles of NaOH. Accordingly, in 25 mL of the acid solution, there were moles of acid. The molar mass of the acid is then g⋅mol-1. This matches most closely with succinic acid, for which the given molar mass was 118.1 g⋅mol-1. Although this represents a 0.6% discrepancy, the error is small enough to identify the acid as succinic acid with a high degree of certainty, given the possibilities listed. 2.

...Exp # 7 Impact of Jet Objectives : • Study the relation between the force produced and the change of momentum when a jet strikes a vane. • Compare between force exerted by a jet on a flat plate and on a hemispherical surface. Abstract The deflectors used in this experiment can be categorised into three geometries. Flat, hemisphere and Vane deflectors are used for this experiment. Calculated force , Fth and the percentage of error will be calculated in this experiment. Theory : Let the mass flow rate in the jet be m . Imagine a control volume V, bounded by a control surface S which encloses the vane as shown. The velocity with which the jet enters the control volume is u1, in the x-direction. The jet is deflected by its impingement on the vane, so that it leaves the control volume with velocity u2, inclined at an angle β2 to the x-direction. Now the pressure over the whole surface of the jet, apart from that part where it flows over the surface of the vane, is atmospheric. Therefore, neglecting the effect of gravity, the changed direction of the jet is due solely the force generated by pressure and shear stress at the vane's surface. If this force on the jet in the direction of x be denoted by Fj , then the momentum equation in the x-direction is : F j = m(u2cos β2 − u1) The force F on the vane is equal and opposite to this, namely Fi = m (u1 − u2 cosβ2 ) For the case of a flat plate, β2 = 90°, so that cos β2 = 0. It follows that Fi = m * u1 ...
