EXPERIMENT 2 Measurement of g: Use of a simple pendulum OBJECTIVE: To measure the acceleration due to gravity using a simple pendulum. Textbook reference: pp10-15 INTRODUCTION: Many things in nature wiggle in a periodic fashion. That is‚ they vibrate. One such example is a simple pendulum. If we suspend a mass at the end of a piece of string‚ we have a simple pendulum. Here‚ the to and fro motion represents a periodic motion used in times past to control the motion of grandfather and cuckoo

According to Ross (1995)‚ an efficiency measure is a tool to assist in healthcare planning and development. The definitive objective of performance measurement mechanism is to support and accomplish the hospital mission‚ vision and goal. To promote and achieve the hospital’s goal‚ the evaluation processes need to be done broadly. As a hospital administrator’s their main aim is to ensure effective and efficient

or the volume of a gas evolved. In this experiment‚ the method of continuous variations will be used to determine the mole ratio of two reactants. With this method‚ the total number of moles of reactants is kept constant for the series of measurements. The property that is going to be measured is the change in temperature. The temperature change‚ or the heat produced‚ will be directly proportional to the amount of reaction occurs and to the total extent of it. The optimum ratio‚ which is the

PDP Physics Lab Report – 01 NAME: Wang Xueqian DATE: 2014/06/21 Introduction In this experiment‚ we will investigate the relationship between the linear speed of an object and magnitude of centripetal force acting on it. We will use a stopper moving in a circle to create an upward force on the hanging mass; at equilibrium‚ the upward force on the mass will exactly equal the centripetal force.

MATERIALS AND METHODS This experiment contained two parts‚ a “PART A” consisting of blood pressure measurements‚ and a “PART B” consisting of linear displacement measurements. The equipment used in “PART A” consisted of an OMRON manual sphygmomanometer with a stethoscope attachment as the manual blood pressure meter‚ and a ReliOn Manual Inflation Blood Pressure Monitor model HEM-412CREL as the automated blood pressure meter. The pressure accuracy of the automatic meter was 3 mmHg and held a displayed

determination of amounts of components in a particular sample. Accuracy and precision are important in data acquisition to be able to acquire substantial results in the end of the experiment. To attain such goal‚ replication of measurements must be performed. The reliability of the measurements may then be evaluated through various statistical parameters [1]. Among the acquired data in the course of the experiment‚ it is possible that not all data are considered valid. Invalid data are called outliers‚ values

skill to make exact measurements. Take for example if a group of students were performing in a lab and a step in the procedure was to measure a piece of metal. They were told it was 5 centimeters long; however one student may say that its 4.9 centimeters long or 5.1 centimeters long or 5 centimeters long. The point is that none of the students can come up with the totally exact length of the piece of metal. Because of this there will always be uncertainty with any measurements that are taken. Even
