Static and Kinetic Friction Objectives:- * Use a Dual-Range Force Sensor to measure the force of static friction. * Determine the relationship between force of static friction and the weight of an object. * Measure the coefficients of static and kinetic friction for a particular block and track. * Use a Motion Detector to independently measure the coefficient of kinetic friction and compare it to the previously measured value. * Determine if the coefficient of kinetic friction

This section analyzes and presents the results of the two trials conducted‚ including the trial in which Hydrogen peroxide(H2O2) was denatured by a cold catalase solution and the other in which the Hydrogen peroxide(H2O2) was denatured by a hot catalase solution. The experiment conducted displayed signs of experimental error as there were many situations in which the materials provided could have faulted. Theoretically speaking‚ from the inconsistent values provided for the pH levels‚ a possible

Substrate Concentration Question: How does concentration of potatoes affect the amount of oxygen produced with hydrogen peroxide and potatoes (enzymes)? Introduction The enzyme used for this experiment is Catalase. Catalase is inside mostly any living organism which uses oxygen. Its job is to break down hydrogen peroxide‚ into oxygen and water. (Formula) 2H2O2 ---> 2H2O + O2 (lab manual). There are limiting factors which if altered‚ can alter the procedure of the reaction‚ such as temperature

Change in the color of litmus from purple to pink or pink-red throughout the tube. Upon further incubation a white ring of litmus forms at the bottom of the tube at the pink-red color is now present only at the top of the tube. Still further incubation leads to the formation of a rennet curd at the bottom of the

wood block across a surface to determine whetherthe surface area ofthe block orthe type ofsurface affectsfriction. We found that the surface area of the block did not change the coefficient of kinetic friction‚ while the types of materialsin contact were directly related to the coefficient of kinetic friction. INTRODUCTION Friction is a part of our everyday life. Nearly every movement we make involves friction‚ and we have instinctively learned to take advantage of friction‚ or the lack

In the lab‚ the purpose was to standardize a KMnO4 solution than using it to evaluate how close a H2O2’s concentration was to its labeled concentration. In this lab‚ it was decided to compare the concentration of new Publix brand hydrogen peroxide to an old sample of the same solution. From the data collected in the first part by titrating a solution of FeSO4*7H2O with the KMnO4 solution‚ it was determined that the concentration was .028M MnO4-. This was able to be done because a known amount of

EXPERIMENT 1: TITLE: ISOMERISM AND KINETICS IN COORDINATION CHEMISTRY OBJECTIVE: 1. To prepare and study the kinetics of the interconversion of some of the isomers of a typical coordination compound. INTRODUCTION: Isomerism played a central role to establish the basic concept in coordination chemistry while reaction kinetics of coordination compound is known as the area of continuing intense research activity. The mechanism of the reactions of coordination compounds relevance

The experiment was conducted at the Human Kinetics Program (HKP) Building in the University of the Philippines – Baguio. The terrain was prepared by distributing an even layer of gravel on the ground‚ and the background was covered by black cloth spanning the length of the terrain. The subject was also dressed in black to match with the background. The boules‚ jack‚ and significant joints and points on the subject’s body were marked with green bands to contrast with the background. A throwing circle

Combustion Background For this science experiment‚ we will be looking at the differences in calorie count between a food label and and the amount we measure in a lab. For this lab‚ we will be experimentally measuring how many calories are in different types of food. Before we begin the lab however‚ we need to investigate the science behind it. Firstly‚ we need to figure out if this project is even possible. Luna Abdallah et al created an experiment making it possible. To measure the amount of calories
